Reason: Not in shape, no stamina.

I've played for 4 years, so I do know how to play football but I took 2 years break from football (soccer) so now I have no stamina at all. But I applied for a private trainings and such to get me back in the game. I am worried that I will get kicked out of another team which I asked if I can join. Football is my passion and if I don't get to join a football club, what other choices do I have? Should I give up my passion? Which I don't want to. I'm already in the 2nd division 1 step below champions division.
