I just wanted to offer some support. I am not on prednisone, but hopefully others here can jump in and give you some advice on the side effects, puffiness, etc. I can only imagine how frustrating and discouraging the side effects of that medicine can be. Please hang in there and don't stop living your life because of what this drug does. People can be very insensitive. Don't listen to them. (Easier said than done, I know). This drug may very well be saving your life. So, do what you can to rest, to eat right, to exercise when you feel like it - even if that means just walking laps around your house or apartment. Never give up or give in to this disease. You are worth the fight. And those people who say such ugly things? Forgive their ignorance and let go of it. Every ounce of energy you have should be focused on your healing. When you are better, you can give them a piece of your mind, if you feel the need.
You are never alone here.
