Hi, baggytrousers,
Hurting and not knowing why is bad enough, but to feel you must hide your pain like a wild animal in the jungle is extra bad. I think it might be helpful to tell your mom or dad you just aren't feeling so hot, you don't have to be too specific about the cutting yet, just ask if they could help you get an appointment to see a doctor. When you see the doctor tell him you are feeling very depressed and anxious, and could he refer you to a psychologist. It is very common for mental and emotional issues to intensify in one's teen years. These are the years we put together our adult identity. This is hard work, and we all could use a little help through these times. Your family may already suspect you are not happy, and don't know what to do for you because no one is communicating.
