Sprained ankle help????? ?

I sprained my ankle about three months ago in soccer. I have been playing on it with my docotrs permission while wearing the brace my docotr gave me. The doctor said I won't fully heal until i rest it for a couple of weeks. I don't have the time to rest it bc of high school season. I was wondering when high school season is over and I rest it for a couple of months, will it fully heal back to normal?? Or will have been on it too long??? By this time it will have been 6-7 months. Thanks
