What should I do if I have nowhere to go?

[SmallKoy]

I feel like it's nearing the end for me being at my alcoholic mom's house, because we are driving eachother nuts and both want eachother gone. I can't afford a place by myself, and I can't even afford a place with roommates. What can I do?? I feel like I'm stuck here until she forces me out and then when she actually does force me out if ever, I don't know what to do. Be homeless?? What do I do if I'm homeless? Idk anymore.
