Personally, I don't think any of you reading should kill yourself; you are you. Nothing else matters. I can't change your mind though. I'm a person who's writing this in the early morning. Probably not a good source, but I'll try to redirect you to professional help.

1. You should go to a therapist. Talking about why helped me personally to understand why I wanted to harm myself. It talked me down, let me reflect on everything. It helped so much. Then again, therapy is NOT for everyone. You should try it, and see if it helps you.

2. Get medical treatment. Talk with your doctor about this. You might have depression, which the symptoms  can be reduced with prescriptions. This won't remove it completely, but it will help. You should do other things along with this to help.

3. Talk with someone anonymously.
Talking with someone is great, but some people have trouble with trust. So they call a place that treats everyone anonymously. Here's the number I know. (Sorry I don't know more.)
1-800-273-8255

Again, I am NOT a professional. These are some ways I have coped.
