Hello Roxanne and welcome to the forum.
That must be so frustrating to put in so much effort and not lose the weight. I never realised the types of things that can make it so difficult until starting on this forum.
I am sorry I am not much help here as I don't know what assists with weight loss when you have a medical condition that can prevent or hinder it.
Hopefully others will have better input.
At least the exercise is excellent for your body and your heart will be loving it.
Good luck with everything.
