[The Cyborg]

I have had a very similar problem that you had, only with marching band. I was in marching band for the first 2 years I was in high school, and I loved parts of it, but hated most of it. The negativity associated with competing with other bands made me uncomfortable, and there were lots of conflicts within the band that made me stressed. I've had some great friends who were in marching band, though. Then I discovered FIRST, and realized where my true niche was. It was a tough decision to give up marching band, but in the end I still saw my friends every so often and I've had a huge burden lifted off of my back. I believe to this day that I have made the correct choice here.

So basically, do what you like to do. If you hate being in football, then don't be in football. If it's for your friends, then feel free to keep in touch with them via Facebook and whatnot. Don't put yourself through something you don't want to do much for the sake of others.
Also, having a job especially in this economy and this time in your live is extremely important as you are getting ready to prepare yourself for the life ahead of you.
