I am also 5 foot 3inches and also weigh 192 lbs, yes it is very depressing. I have joined a gym and have been walking 1 hour every day on the treadmill, however I am so exhausted after this I have to lie down. I can sympthasize with you, as this is the heaviest I have ever been, naturally people assume that Crohns Disease sufferers struggle to put on weight, but Crohns seems to affect people differently. The weight came on while I was on steroids, called Predinsone,. however now I am in remission I want to lose this excess baggage.
I feel your pain. I don't get diarrhea, and when I'm not flaring, I eat normally - which is too much in my case! I love food, too.
Part of my problem is that I went 3 months without eating anything solid so I gorged once the medication worked and I was able to eat again.
I have kept most of hte weight off but it's slowly creeping back on. I hope walking each day will get some of it off.
