What to do when you feel broken inside? Or lost..

I have been hurting and I feel so lost. I was crying earlier. No one knows my pain. I don't feel like anyone cares.

I don't know what to do with my life and I feel so frustrated and, at the same time, overwhelmed with things. I don't know what to do. I don't have anyone to talk to. Everyone is so busy with their lives or with their problem and I don't want to add up. I'm so miserable inside.
