So is there any reason why you can't live at your grandad's? And could you move into a shared house like I said on the other thread - you don't need friends to move with, you can look for advertised rooms. I have lived in a LOT of houseshares and actually find it's better not to live with close friends as you end up getting on each other's nerves, it tends to work better with people you don't know so well.

Please don't give up. It will get better, honestly.
