Believe it or not i also feel lonely all the time, but in no way do i handle the problem by cutting. What i do is just talk to a close friend, or do something that i love to do. Try talking to someone who you are comfortable with, you can even talk to someone on here if you wish. But what ever you do, remember cutting is not the answer it only makes things worse.
I'm always here to help you, pm if you would like. :)
Be honest and let me know.
