You say your boss knows, I'm sure he/she, will back you up for the caring person you are. I know its hard in the healthcare field, I also work in that area. Although my boss, or co-workers know nothing about my dx, they are actually very kind to me. Just last month I did no-call, no-show for a week. I just told them I had a mental breakdown, and they were good with it! My good actions, outweighed my mistakes, as I'm sure your good will shine through! Gossip is also dealt with effectively where I work, so that probably played a part too. Wishing you the best
