Is this self harm normal?

I hope that you are being treated for your mental and emotional problems. You need to discuss this with the psychiatrist who is treating you. If you aren't seeing a psychiatrist you must do it. You can go to the site nami.org which is the site for the National Alliance on Mental Illness. On their site you can find the phone number for your local chapter. They are there for support, information, and they have the best resources for the help that you need in your area.
