I think I'm nostalgic...?

So in late July of 2009 I moved states, the state I had moved from I had essentially spent my whole childhood in and still remember that summer as if it were yesterday. Also right before summer my favorite band, green day released their album and I loved it and still do to this day, only one problem, every time I hear a song off the album my mind immediatey jumps to that last summer and begins going through the whole memories thing and i feel like I have a giant pit in my stomach and almost want to cry (were all humans). This summer I was thinking of going back and visiting and my old friends said they're glad I'm visiting (I was sort of the lynchpin of our group). But should i go and have more memories my mind goes through or just stay where I am and try to stop thinking about the past? (if I were given an opportunity to move back I would take it in a second, not that i don't love my new home but I had established friends and places and all.)
