Honestly, and I know this is going to go against what some others have said thus far, if you're actually in wrestling season, then I would suggest really decreasing the amount of weight training that you do. In season is not the appropriate time to be trying to build muscle and strength, that's what the off season is supposed to be for.
You sound like you've either wasted the off season not preparing for wrestling, or you've been doing a very ineffective program.
What you need to do is just maintain what strength you do have, really practice your wrestling technique and just do what your coaches tell you to do. Once again at this point your focus should be one conditioning and technique. Do push-ups on outside of practice, see if you can find a team mate who is interested and practice technqiue together, try to push each other to be better.
Hopefully when this season is done you'll take this as a learning experience and use the upcoming off season to really work on improving your strength and (if need be) building some muscle.
