I am so sorry. I hate to know of anyone who feels that way and especially at such a young age. You cannot always control your circumstance, and bad things are bound to affect you at times. Even though your situation may seem desperate, remember that you are not alone and that sadly nearly everyone is coping with some type of problem. One thing that you should do is share your feelings with a mature, trusting friend. Telling others can diminish the intensity of your feelings. It can also give you a different view on the problems you face. You can also pour out your heart to God in prayer. A wonderful website you can to is www.jw.org. It has a whole section for teenagers. I hope you look at it and find encouragement.
