What should I do?...?

I have aspiractions to play college football then hopefully one day professional football. Im a sopre starting on varsity at linebacker and I started the first three games of the season and did really well and then a week later I had a bad game. I just figured, well everyone has a bad game at some point. Then during the week after my bad game I stretched my tendons in my ankle and severely sprained it. I was out for two weeks. I came back two weeks later and last night I played a team that was ranked in the state. I made about 8 tackles but I also got driven back at times and pushed around because I had no balance on my ankle so I had to get helped off the field during the fourth quarter. When I come back, I think I might be replaced for the remaining three games, if I even come back at all. Im not sure yet. Do you think that I should still pursue my dream to play college football?
