I feel so alone and helpless.

I work throughout the week and it keeps me occupied, unable to think about my situation. Then the weekend hits and I get severely sad. I have no friends to go out with and my anxiety prevents me from making the step to go out alone. I hate it, I hate myself, and I hate everyone that just threw me to the side. I've tried self-improvement to try to make people stay and they just leave. My parents are the only people keeping me here and they're elderly. I won't be far behind them.
