There is also a Depression forum on this site. Both it and this Heart Disease forum are peer support sites, as Flycaster mentions. There are Doctor Forums on here as well, though, where you may be able to get a physician to answer your question. I haven't tried any of the Doctor Forums, so I don't know the details of that, but if you're interested, click Forums above and then Doctor Forums. Good luck.
This is probably a better question to ask of your doctors, this is a support board and may or may not be answered by health professionals.
You need to be evaluated for the chest pain, and you should consider doing a much slower taper off of the Paxil. Paxil is a hard one to get off of. It might take a long time to get off of it completely. I'm sorry you are suffering so much.
