I would talk to your doctor, maybe an increase in celexa would help. Or as said another SSRI. I would give it another couple of weeks to kick in though.

the typical dose range is 10 to 60 so ask doc about upping it to about 30 and try it for a few more weeks, if still no help then try some other type of antidepressant
celexa is one of many prozac type meds
