Hi, Buffy !
Your medical situation makes it difficult to lose weight, but not impossible. Remember, this isn't a diet. Part of living a healthy lifestyle is learning how to take care of your body. Weight loss isn't just about cutting calories. We need to take care of our insides. Because when our insides are healthy, that reflects on our outsides.
When you're stressed out and feel like you want to take a nose dive into comfort foods, consider taking a walk instead. Walking is not only great cardiovascular exercise, it's a great way to reduce stress. I'm a firm believer that stress is a neglected aspect of weight gain. if a person could reduce their stress. They'd automatically reduce their waistline.
There are better ways to cope with stress that don't involve food. try a bubble bath. try listening to relaxing music. try a hobby. in fact, I'm encouraging you to take up a hobby like knitting, sewing, painting, etc... do something crafty that keeps your mind and fingers active. Because when your mind is busy, you won't think about food. having a hobby is another good way to relax and relieve stress.

Mostly, you do have to listen to your doctors since they are there to help get you well again. I know taking the medication is making you bloat as well as depressed, but every little bit DOES make a difference. If the only healthy thing you were to do for yourself today was drink 8 glasses of water, that's still a step in the right direction.
And that's what you're trying to do, take steps towards a healthier lifestyle.
