Its never easy in a break up, you just have to stay busy try not to think about it. i know thats alot easier said then done, but what else can you do? It sounds like you miss having someone to do all that stuff with. Once you get comfturable with your first girlfriend it seems perfect, but honestly once you spend a substantial amount of time with any girl well almost any girl and realy get to know eachother its always fun. I'm just getting out of a relationship too but you gotta keep your head up, everyone gets their heart broken you just gotta bounce back and keep a look out for another girl you'd be interested in. Hang out with your firneds concentrate on school (or work) the more you wallow in your own self pity the harder it will become. Your friends sound like they're there for you, meet them half way.
