I have no one

I have no one anymore. I lost my friend because she wanted to be with her abusive boyfriend and I told her I couldn’t just sit back and watch everything happen. My other friend is in a relationship and never has time to respond to messages let alone to talk. And I just lost the only guy I’ve been talking to and chilling with for the past year and a half. I have no one. I’m a failure working at a gas station. I can barely afford my rent. I don’t know what to do.
