I am sorry to heal of your many physical ailments. I agree with Dee tho, if your current doctors aren't concerned about how you feel about your medications then it may be time to look for a second opinion.
It must be really tough, being on that much medication. I don't deal with many chronic physical conditions, but I do suffer from some mental stuff. At one point several years ago I was taking I think 5-6 or 7 meds every day, and I know it made me feel way out of it and not like myself.
Best wishes,
