I am glad you posted this--please reach out to your school counselor, friends, and keep posting. Of course, tell your parents (but I can tell that telling your parents bad news is what you are really avoiding--sometime we think about suicide because it is actually easier to think about death than the things that are really troubling us). If you think you might act on it--it is crucial that you tell someone. Please read this link: How To Help Yourself Get Through Depression on a Day-To-Day Basis plus the related links (more depression links) having to do with suicide. I made an attempt and it may be my biggest regret in my entire life! I really wish I had not gone and done that but I can't ever take it back. Please don't do what I did!
