Soccer Girl Problems: Injuries

So I've been planning on quitting my indoor team for quite some time because well...they suck. I can't play with beginners. It's not a challenge and my teammates don't try. Last week an outdoor team offered me a spot and I was ecstatic. Finally something more competitive right? I check them out tomorrow. Problem is..last night during my second indoor game I was changing directions really quickly and I'm pretty sure I pulled something in my foot. It hurt to walk/run and this morning I can't put weight on it. Like WHY does this have to happen to me now?! I already have ankle problems on my right side. I just...my body..it hates me. I think this might have something to do with changing my style of running shoes. The people at the store recommended it for my foot type and now I'm thinking they had no idea what they were doing. I was really looking forward to a new team and now I can barely walk.
