You shouldn't give up yet. Maybe you can tell it family you need some help? Then get a part time job and pay for your expenses and maybe look into a cheaper school where you can get a good enough education for a paying job that u can use to get up on your feet and keep going with your life. Honestly relationships are a bit overrated and maybe if you're feeling lonely you could spend time with your family, and show them your plan for the future and show them how you aren't a failure and how you can get through this with some sort of plan. I'm sure that if a plan is given to them they'd be more able to help you and understand that you aren't a failure. I also think ur problems are something that I can't really understand at all like you can, I'm just providing suggestions based on the info given. But it's fine if u were just venting or smthing and if that's the case ur welcome to vent to me if you want to cuz a lot of times people just need to get stuff out. It's also fine if you actually feel like talking about ur problems and if you feel like you need to, I can respond to messages. So I hope you feel better and try to make it through a bit longer, because maybe, just maybe it'll get better. And just take it one day at a time, for me, that helps me cope, maybe it'll help u
