I am thinking of killing myself?

Death is a permanent solution to a temporary problem. Have you tried talking to a professional? Do you have friend or family you can talk to? I know exactly how you feel because I have been there many times. What you should do is find one good thing in your life that makes you happy and focus your attention on it. I know a strangers words have very little value but please take it for what its worth. You may think no one cares about you but I'm sure they do. There is always someone in a persons life that cares, even if it is only one person. I think you should seek help. You seem totally broken and in that state its hard to think clearly. Please keep your chin up. Though I am a stranger, feel free to email me if you need to. Good luck Sweetie.
