Reaching 30 and I don't know what the fuck I am doing

So, I need to vent out my frustrations somewhere. I am 29 and I don't know where life is going.

I am stuck in a dead end job that's taking my career nowhere. I work in one of those call centers where people in their 50s still work as agents. Not by choice btw, life threw me here and I didn't have an opportunity to take risks with money for most of my life. I want to get out of this and I'm trying but god freaking damn I'm exhausted. I'm in no position to take a break because of bills and shit.

Love life went to shit, pretty much never had one. Friends left too and I now pretty much stand alone. It was okay for the most part but now it's catching up. Loneliness is creeping in every aspect of my life and every cell of my body.

I feel like... I will give up soon. On everything... And I don't know how to prevent that.
