Suck it up or become a forgotten statistic.
You want to have friends and family? Then stop complaining on the internet and go get them. It won't come to you because you are the arbiter of your life. The decision is in your hands.
A degree is the difference between being a wage slave and having a career. Do you want to spend the rest of your life living paycheck to paycheck in debt you'll never pay off, hoping you don't end up fired and bankrupted one day? Then stay in college. College students usually have some stressful living arrangements (something I now know better than anyone else), but it isn't even comparable to trying to live on minimum wage.
Going to a monastery isn't going to help you, nor will any religion. It's a cop-out, a way to escape the real world for good and live in a made up one. You want that because you don't like your current situation, but you aren't solving your problems, you're running away from them.
Who cares if the mental health system is a fraud? You don't need their pseudo-science, or their judgement of you as broken. If you're the one who thinks you're broken, then obviously you already know what's wrong and can start fixing it.
Why do you hate yourself? Why are you guilty? We can't give you advice unless you tell us why.
But if you really want to die, then die and achieve a state of ultimate failure at your one and only real job, to live. We can't stop you. No one can stop you. Only you can stop you, and you're still here.
