I understand and know the feelings/thinking of the medications "taking away" pieces of your own unique personality. I've fought my therapists with the medications for this very same reason. However, my personality is still there, it's just not as "intense" as it was. Good and bad.
The best question I was asked that calmed this worry of mine is, what's worse? Having the mental torture and painful mind frame that I had before the medications, or being on medications that calm the painful thoughts and feelings while it calms aspects of my personality; Good and Bad.
With reductions of holes in walls, screaming like a Banshee is at all time lows, and increase safety of man kind, proves I made a good responsible decision to stay on medications.
