Why do i feel so down all the time.. want to stop cutting but can't/ suicidal thoughts. help please?

It is imperative: That you obtain professional help. If you have a suicide plan that you are going to carry out then you need to be seen now at your nearest emergency room. A friend or relative could drive you or you can call 911 for emergency services. If you aren't in therapy - you need to be. Dialectic behavioral therapy could be particularly effective. Don't lose hope. Things can get better.

Cutting: Meds and therapy together are your best bet. Get a psychiatric evaluation for what ails you, and what cutting means to you as well as anything else that may be going on. Then get a referral to a reputable psychotherapist to help with the emotional issues behind cutting. DO THIS RIGHT NOW. TURN OFF YOUR COMPUTER AND GO TO YOUR LOCAL EMERGENCY ROOM OR DIAL 911 IMMEDIATELY.
