Not that I don't agree that the OP should indeed move if it's affecting him that badly, but I'm sick and tired of people throwing this particular comment around.
If you're in such a financial position that you can just decide to move home on a whim, then I envy you. I really do.
Then get a new job somewhere else in the country?
Why move there if you didn't do your research?
Peoples lifes differ, but the just I get is the guys single. ( I mean no kids) and young. It isn't that hard to look for new jobs, or at least make an effort to do so rather than just moan about it. Do something.
