Sounds like you kinda hit rock bottom. That sucks but I think you can make this into a positive.
There is some real opportunity here. Think about it. You are still pretty young, you say you are isolated so there's no people to take into account when you make decisions. No girlfriends, children etc. You don't like the place you live. You have no job/career keeping you there.
Now is the time to do something fun.
Blindfold yourself and pick a spot on the map.
Hitchike there. Who nows who you'll meet
Find a random job, like Mc Donald's or farm work or something else that is easy to get. Who nows where this will take you.
Get a cheap place to stay, camp out, sleep under a bridge for all I care. Try to live very cheap. Be creative
Work until you can afford a moped that is in decent working order and have some money to burn. Quit your job.
RIDE IT. just in random directions till you bump into something. Maybe this will be a job, a place, a friend, a girlfriend you now something. Then start from there.
Now you have gained some life experience, and you found a place to start over. Clean sheet and stuff.
To me this sounds a whole lot better then hating yourself and posting on MA.
GO DO IT
