I dont need people to function

I dont need anyone. All i need is my guitar my self harm addiction and maybe some pain killers. I can function just fine in society. Well that is if people would actually leave me alone. But everytimes they try to make an effort to talk to me. Its wierd, why would they go out of their way to make me misserable commenting on my cuts. I know i cut myself, i know people think its bad. But i need to do it. I lose my grip on reality without it. Im literally going insane without it. God i wish people just wouldnt judge me for who i am its so akward.
