I know what you are going true! I am MS patient for years now and bad (MS)strokes became pretty common to me alas. Even lost eyesight for one eye but recovered from that against all expectations. Only 50%, but that is better then nothing! I have been the last halve year in bed due to a next bad stroke. I am fighting back and will never give up. Slowly picked up training again lately and doing very well. It is hard, but not impossible. Shooting no heavy bows isn't a problem with the amazing good bows they make these days. I am around the 45 lbs, and enjoying it.
Take every days as it comes, and count your blessings bro! Forget the bad days and only count the good ones! God will carry you, don't loose faith. Hang in there!
