What does it matter anymore?

What does it matter anymore? I seems like nobody cares so why should I? All I can do is feel depressed and cry. I want to cut really bad to end this pain. I'm so scared. Scared of myself and scared of life. I feel almost like I don't want to go on anymore. I'm scared to be by myself but I can't stand to be around others right now. I've took time for myself today and went for a walk. So far nothing has worked. I've been feeling like this for awhile now and I'm tired of it. I'm tired of living this way. I'm just plain tired, emotionally. I feel like I can't do anymore. I really think I'm done with this all.
