Hate your body?
Get a blade, take it and go into your bathroom, then take all your clothes off. Stand up and look in the mirror. Just stop and look for a second, even if you hate what you see. The, imagine your body covered in scars, cuts and bruises. Imagine yourself, months from now hiding your body, apologizing while you hurry to push your sleeves down, Saying it was just your dog/cat, having to cover up your wrists all the time, lying about them.
Now back to normal, which do you prefer?..Exactly. Put down the razor. Put your clothes back on. Leave the bathroom. Go call someone you care about and tell them you love them.
Don't ever touch that f*cking razor ever again.
