I suggest doing a before and after check list. Include symptoms as well as quality of life. If both pictures have very little or no difference, your meds are ineffective and ultimately a waste of money. Which means you have to re-strategize, try new meds, different therapy, even new coping mechanisms. No point in using meds that are not beneficial.
Also, you can't judge a meds effectiveness based on withdrawl symptoms, its not a very accurate indicator, plus alot of people complain about meds causing the very symptoms they're trying to treat, 2 biggies are depression and anxiety, so you may want to address this with your pdoc too, it may just be the reason you remain depressed.
Hope you figure it out and formulate a health plan that works
