What happens once you kill yourself? Because I'm ready to go.

You wanna know what happens once you kill yourself? Your mother comes home from work and finds her baby dead and she screams and runs over to you and tries to get you to wake up but you won’t and she keeps screaming and shaking you and her tears are dripping onto your face and your dad hears all the screaming and runs into the room and he can’t even speak because the child that he loved and the child that he watched grow up is gone forever and finally your little sister runs into the room to see what all the fuss is about and she sees you dead. The person she looked up to and loved. The person she bragged about to  her friends, the person she wanted to be just like when she grew up, the person that made her feel safe. But she’s never really going to get to grow up and smile and laugh and love because she’ll always be consumed with this feeling of missing you. And now there’s something missing from your family and they can barely look at each other anymore because everything reminds them of you but you’re gone and hurts more than anything. and you think that your mom never cared because she was always busy and yelling at you to finish your homework and clean your room and forgot to say I love you sometimes but really, she loved you more than anything and she doesn’t leave the house anymore, she can’t even get out of bed and she’s getting thinner and thinner because it’s too hard to eat. Your father had to quit his job and he doesn’t sleep anymore, every time he closes his eyes he sees his baby dead, and the image never goes away no matter how much alcohol he drinks. And at school your best friend sees that your seat is empty and she gets this sick feeling in her stomach and that’s when she hears the announcement. You killed yourself. And suddenly she’s screaming and crying in the middle of class and no one even bothers comforting because they’re all  busy sitting there staring at your empty seat with tears dripping down their cheeks and all she wants is for you to hug her and tell her it’s gonna be okay like you always did, but this time, you’re not there to do it, everything is dark now that you’re gone and her grades are slipping, she barely goes to school anymore and she ended up in hospital after taking too many pills because she wanted to see you again. the girls who used to make fun of the way you dressed feel their throats get tight, they don’t talk to each other anymore, they don’t talk to anyone, they’re all in therapy trying so hard not to blame themselves but nothing works. and your teacher who always gave you a hard time stares blankly at the wall, she quits her job a few days later. And then your boyfriend hears the news and he can’t breathe, he still calls you a lot just to hear your voice and he talks to you on facebook but you never message him back, he can’t fall in love again because every girl he meets reminds him of you, he’s never going to get over you, he loved you and he cries himself to sleep every night, hating himself and slicing his skin because he couldn’t save you and he’s never going to hold you in his arms or hear you laugh again. Now everyone who knew you, whether they were a big part of your life or someone you passed in the hallway a few times a week, they carry this aching feeling around inside them because you’re gone, and they miss you, and they don’t know why you left but it must’ve been their fault and they should’ve stopped you and they should’ve told you they loved you more and that feeling is never going to go away. And so you killed yourself

but you killed everyone else around you too.

Drake Equation

What do we need to know about to discover life in space? How can we estimate the number of technological civilizations that might exist among the stars? While working as a radio astronomer at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived an approach to bound the terms involved in estimating the number of technological civilizations that may exist in our galaxy. The Drake Equation, as it has become known, was first presented by Drake in 1961 and identifies specific factors thought to play a role in the development of such civilizations. Although there is no unique solution to this equation, it is a generally accepted tool used by the scientific community to examine these factors.

N = The number of civilizations in the Milky Way Galaxy whose electromagnetic emissions are detectable.

R∗ = The rate of formation of stars suitable for the development of intelligent life.

fp = The fraction of those stars with planetary systems.

ne = The number of planets, per solar system, with an environment suitable for life.

fl = The fraction of suitable planets on which life actually appears.

fi = The fraction of life bearing planets on which intelligent life emerges.

fc = The fraction of civilizations that develop a technology that releases detectable signs of their existence into space.

L = The length of time such civilizations release detectable signals into space.

Original estimates

R∗ = 1 yr−1 (1 star formed per year, on the average over the life of the galaxy; this was regarded as conservative)

fp = 0.2 to 0.5 (one fifth to one half of all stars formed will have planets)

ne = 1 to 5 (stars with planets will have between 1 and 5 planets capable of developing life)

fl = 1 (100% of these planets will develop life)

fi = 1 (100% of which will develop intelligent life)

fc = 0.1 to 0.2 (10–20% of which will be able to communicate)

L = 1000 to 100,000,000 years (which will last somewhere between 1000 and 100,000,000 years)

Within the limits of our existing technology, any practical search for distant intelligent life must necessarily be a search for some manifestation of a distant technology. In each of its last four decadal reviews, the National Research Council has emphasized the relevance and importance of searching for evidence of the electromagnetic signature of distant civilizations.

Besides illuminating the factors involved in such a search, the Drake Equation is a simple, effective tool for stimulating intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for making us realize how much we are a part of that universe. A key goal of the SETI Institute is to further high quality research that will yield additional information related to any of the factors of this fascinating equation. seti.org (read more)

Healing Spell

Two people I care about very much were in a very bad car accident, the healing process is very slow and painful and expensive… This is a spell to help for a speedy, healthy recovery after an accident or illness, to keep them safe and healthy for the future, and to promote peace to help them get passed this horrible event emotionally. 

Tools:  - Altar dish or bowl  - Pink candle for love and care  - Pink Salt for cleansing, healing, love and care  - Queen of Pentacles to channel maternal care, love, support, compassion, nurturing, security, practicality  Herbs:  - Bay Leaf: healing, protection - Chamomile: Peace, love, healing  - Cilantro: health, love, peace, protection - Cloves: banishing negative forces  - Cramp Bark: healing, female energy (maternal energy for care and nurturing) - Lemon Balm: healing, peace - Lavender: relief from pain, discomfort, and anxiety  - Rosemary: protection, feeling youthful  - Sage: long life, peace  Crystals:  - Amethyst: healing, soothing, peace  - Citrine: happiness, positivity  - Rose Quartz: love, care  - Black Tourmaline: protection 

How To: 

Step 1: 

Place the dish in the center of the altar, fill the base with pink salt to start with a cleansed base and to promote healing, love, and care. Make a small round space in the center and use melted wax to stick the pink candle in the space. 

Like so:

Step 2: 

Place the herbs around the candle, over the salt. Focus on your intent as you spread the herbs in a circle around the candle. Once that’s done, place the crystals over the herbs. Then place the Queen of Pentacles tarot card under the dish/bowl as a way of charging the spell. 

image

Light the candle for as long as you would like each night. Every time you light it, imagine the person being their usual happy, healthy, bright personality, loving self. I want them to be ok very badly…  Also huge thank you to @starlesswitchybird for their Inspired Healing post, which was a huge inspiration for this one. I hope you don’t mind the changes to it.
