Hey man. I graduated HS back in 2007, so I've lost contact with most of those friends for quite some time now (probably for the best). This summer I started at a new university. I haven't made any solid friends yet because summer semester is kinda iffy when it comes to whos sticking around for fall, or the reasons behind why they're taking a summer class. However, I sympathize with you, as I too know no one as of yet. But, just keep an open mind, say hello to your neighbors in the classroom, and if you get talking to anyone, be sure to mention your hobbies quickly (weight lifting and such), so you can screen out the HAES people.
