First, she shouldn't have stopped the trazadone abruptly -- she should have tapered off it as slowly as needed, just as she should have done with her pain meds. Her brain is very stressed and she's suffering withdrawal both physically and psychologically. (Make real sure she never does this with cymbalta -- that's the worst of the lot to stop taking). Those pain pills are happy drugs and stopping them abruptly makes anyone feel empty -- the high is gone. That will take time even apart from the withdrawal caused by the difficulty the brain is now encountering working again without these things. I'd reevaluate the speed she did this, and especially talk to her psychiatrist about having stopped the trazadone abruptly. Now, hopefully, this will all pass eventually, but sometimes it doesn't, so safety is key here.
