Workouts for someone with health issues?

I have been doing zumba everyday for over a month but im not sure if my kidneys can handle it much longer. I have a kidney disease where my kidneys make stones 24/7 and its painful to bounce around and dance. I love doing zumba but its very discouraging when my kidneys start throbbing when im doing it. And i hurt for the rest of the day. I cant do sit-ups either because of a hernia that acts up when i do them. I hate my body. Im skinny fat im 123/124 i went down to 120 but it didnt stay that way. I just need some good workout ideas that dont cause me to be shaken up. Im so down on myself right now because i hate how my body looks. I used to be 115 with a great body and now i cant seem to get rid of my baby fat and its getting harder and harder to workout cause of the pain. What do i do? Help!? Im working on loving my body and its absutely not working. I cant stand the way i look and i would give anything to be able to fit comfortably in my pre baby clothes. Why buy new ones when i have perfectly good clothes that i can hopefully fit in by working out and eating right. And i had my baby 20 months ago, i should be able to get rid of this fat. I know it takes time, but seriously i dont know how much bouncing im going to be able to do. I thought about jogging but i dont think my kidneys can handle that either... Thanks yall. Sorry to bug everyone with my problems
