I used to do it to numb, release pain, and stop panic attacks and sometimes the voices would go away for a few minutes. I highly encourage you to seek help and meds. I'm schizophrenic and hallucinations continued to get worse as I aged and escalated to delusional episodes as well as all consuming hallucinations where all my senses were telling me I was somewhere else, by my early 20's. It has taken years of therapy, a few hospitalizations, and many different Dr's and trying different medications to become stable. I'm almost 29 and have been hallucination free for almost two years. I attempted suicide a few times, the last time when I was 15 and I kept attempting suicide when I would quit cutting because the idea of living without cutting was just too much. It's okay to need help and other people. Don't try to handle it alone. Starting therapy young helped me hold on to reality for longer, and learn reality checking techniques, but even those are almost never enough as the illness progresses. Thanks to meds (and God, I believe) I have an amazing life, a wonderful husband, a 6yr old son, the ability to get a job if I needed to (although thanks to my husbands job I am able to stay home and focus on volunteer work). It has been a really rocky road with lots of ups and downs. Navigating meds and the different side effects was hell at times, but it has all been worth it to have the life I do now.
