Atlantean: What do you do when you have a toothache? See a dentist right? How about when you're sick? See a doctor?
What happens if you do nothing? It either gets worse or doesn't go away. Get yourself some help. It will get better, given counseling, time, and perhaps some new meds.
You are not in control when you cut yourself. In fact, it's a red flag when you do things like that that you are not in control. Write down what you are feeling and positive things that you could do to possibly feel better. If you feel overwhelmed with problems, don't look at the whole, take the time to go step by step and tackle each problem one at a time. That way, they're smaller and not so awful. Think a happy thought each hour. For example, at 3pm today, think something happy. It can be anything at all, so long as it's happy. Even something as small as "I had a good lunch today." Then repeat the process each hour. Just as one negative thought breeds more negative thoughts, positive thoughts promote positive thinking.
Get counseling. I can't stress this enough. A counselor can help you get better faster.
And finally, suicide is a final solution for a temporary problem. See a counselor.
