Hey Cheerstoall, I think I know how you're feeling...I graduated from college recently and moved back in with my parents. I went from having so many friends I could rely on to virtually no one I can trust at all--I feel like I don't have real friends here. It's really, really hard, and it hurts. But I think what people like you and me need to do is give time a chance. Moving hurts, but only time and a little bit of effort can keep us going. And sometimes, we need outside help too. The National Alliance on Mental Illness (http://www.nami.org/) has a lot of resources available, even if you're not in the U.S. you can navigate through their website and maybe they can help.
Please take care. There are lots of resources out there, and lots of people in your situation. Things can get better.
