Will my heartbreak ever end?

I am one-month post breakup from this guy I loved very much. We had planned so many things this year, and now that he's "gone" I don't see my year being as enjoyable as I wanted it to. I don't have any friends, he and his circle of friends are my only friends but they haven't spoken to me in a while. Everything reminds me of him, the nice spring weather, certain songs, movies, and even when I'm not thinking about him, I dream about him, and it makes me very depressed. I can't even go out in public because I have now started having panic attacks because of this. Our birthdays are even 3 days apart, and THAT makes it worse because we were supposed to spend our birthday week together. It's been a rough month despite all efforts to cope. I have decided to take a trip out of the state for a while in may to hopefully get my head together, but at some point I have to come back and deal with reality again..

Note: I put "gone" because despite deleting all contact info, we are still friends on Xbox live, but when I reached out to play a game, he didn't respond. I know that there are other guys out there, but ever since I met him I haven't even been attracted to other guys, because he was literally like a male version of me. Sadly, I feel like it's gonna be this way forever. He's the only one I want, but I don't know what's going to happen and it upsets me. Will things get better for me? What's going to happen?
