Weight loss with chronic illness

Kierre-marie • ❤ got engaged August 2016 ❤
Hi everyone.. I'm new to this group.. I'm from the uk, 26 years old 5 foot 4" and weigh 217lbs.. So I'm kinda round lol.. I desperately want to lose weight to fit into a pretty wedding dress and to help me get pregnant.. but I have several chronic health conditions which make vigorous exercise difficult and I always end up giving up when I'm not seeing results.. is there anyone in the same kind of situation who can offer moral support?
