Losing weight struggle

I can’t seem to get rid of my belly.. I had my son 3 years ago and I have tried to eat healthy and I use to go for walks but it seemed to make no difference.. and I have severe asthma so when I exercise I can’t breathe AT ALL.

Is there any supplements or anything I can take or something I can do to lose this fast..? It’s

really effecting me. I use to be 105lbs before I got pregnant, I’m 5’4 and 165lbs now..😞😞😞 any suggestions would be great!

And note anything I eat even healthy makes me really bloated, even if I have just water. I don’t know if that matters or not.!
