I was on lexapro for 2 years, mainly for anxiety, went through a depressive episode. Felt amazing then the drug seemed to "poop out" or lose its effectiveness. I went up and down on the dosage then my doc switched me to Zoloft 37.5 and I'm on Wellbutrin 200. I get anxious from time to time but feel my emotions are numb. I can't explain my emotions cause its tough to feel anything positive from an external stimulus. Being with family doesn't give me that comforting feeling. I feel spaced out and not the "normal". Does this mean that I have been on antidepressants for too long, cause I feel drugged and zombie like you could say. Could it be causing harm now? Thanks
