asthma
"I took this medication last year while going through a bad bout of asthma. I was prescribed 30mg a day (with tapering, so about a week total). After the third day, the anxiety and crushing depression I was feeling with the medication caused me to go back to the doctor, and she told me to come off it immediately. I was not told to taper off, which I now know is a bad idea. I spent a good 10 days suffering withdrawal effects, and had dark thoughts. 

It took me 9 months to start feeling myself again. I had debilitating joint pain, so much so that I was tested for lupus,RA, and other joint/ connective tissue disorders. I was also very depressed. Had take pred before, with bad reactions, this was the worst yet. Never again."
