First, you need to get help.
Second you need to have someone you can talk to.
I started cutting myself when i was 13, i am now 16.
I have a best friend that lives nextdoor to me, and has, for countless years. She cleans her aunt and uncles house once a week for a small amount of money. just to give them some extra help. My friends uncle was a bad smoker and was on oxygen for 10 years. He still smoked, and smoked until one day my friend keli went over to his house and found him dead on the floor, no one else was home. There was nothing she could do, she called 911 and they took away his dead body. I was on vacation when all this was going on, and didnt come back until after. When i got home keli came over and told me what happened, i was very close to her uncle also, so i was upset. but what upset me the most was the fact that she had seven cuts on her body that she intentionally made. That was the day i stopped cutting myself.
Point being, i cut myself for a number of reasons, but the biggest reason was that i could get away with it, my parents do not pay attention to me, and they have never even asked about the deep scars that cover my arms, or the one on my neck. i cut myself so many times that it didnt hurt when i passed out in school and smashed my face into a brick wall and had to get 12 stitches in my forehead. I barely felt anything. I dont like not being able to feel physical pain. The only pain i feel is the mental pain i have caused myself by harming myself for so long.
here i am just rambling on, theres just too much of this story to tell. Just please, dont wind up like me and later realize how much you hurt yourself over nothing.
