panic disorde
"I started Paxil 15 years ago after a stroke. Lately felt maybe it's not as effective my Dr switched me to 40 mg of celexa same as my Paxil. After six days on the new one I felt like I was having problems with weakness on one side and felt like I didn't have long to live etc.  so got myself into a big panic attack. Back on Paxil for now feeling better."
