In addition, I belong to a health club
and experienced no difficulty working out with weights, sit ups, and aerobics since having the full open surgery (laparatomy).
You'll be able to push yourself in time. When I had the laparatomy, part of my ovary was removed along with a fallopian tube. I was completely healed in about 8 weeks. I feel bad for you that you're so frightened about the surgery that you actually fainted.
