I got a concussion at basket ball practice and...?

Well, in a two minute time period a girl backed her head really fast in to mine, a girl threw an elbow and killed my head and another girl took a sucky shot and it bounced off and hit me on the top of the head. After the third time I ped out but only for like a second or two. Anyway i have never had any serious injury before so I was wondering what I can do to make my concussion feel better.
