CassyBecky,
I don’t have CAH but my kids do. However, I have had a lot of experience with steroids. I suffered from bad hives for a long time and lived on Prednisone. It is great if you have to have it but does a lot of bad things. It will cause bone loss, you will gain a ton of weight, a lot of bad side effects. I agree with your doc that you should stay on as low a dose as possible.
I have been on antidepreesents as well and there is nothing wrong with it. You may have a chemical imbalance and just need something to help level things out. Also, with antidepressents maybe you should try some kind of therapy to work through your depression.
Good Luck
Cassy
