Major depressive disorder and ptsd

So my shrink has tried me on yet another new med for depression at40 mg it didn’t do anything her answer to double the dose. One of the anti depressants she tried me on turned my arms and legs to jello I would be walking through the apartment and suddenly for no reason I would be shuffle running and then fall and I couldn’t get up this went on for a week before it dawned on me to stop taking the new med it took another week for the falls to stop.

What medication are you on?
