You will probably notice that you resort to cutting yourself whenever you are upset or under stress. While it may seem that is provides some relief or gets you attention, you seem to recognize that this behavior is unhealthy and only adds to your problems. Cutting can lead to a cycle of behavior that can become a pattern that is hard to break. For more information see TeenHealthFX's response to Cutting Myself.
The best thing you can do for yourself is to get help from a mental health professional. A therapist can help you develop healthy ways of coping with life events that can replace the cutting behavior. It would probably be a good idea to let your parents know what is going on and ask for their help. Sometimes, parents might think you are just looking for attention, and they may not recognize how much you are hurting. Using words to help them to see how much you are hurting will also help you express some of the feelings that you have been keeping inside.
If you cannot get your parents to understand how you feel, perhaps you can find another adult who you trust, such as an aunt, uncle, teacher, school nurse or guidance counselor. In any event, please talk to someone soon. Cutting yourself is a very serious behavior and your life and health is precious.
