I get this all the time and I just blow it off unless the person is interested and willing to listen to what I have to say. It seems to me that the majority of people who denounce MI/psychotropics the loudest...are in denial and probably need to be taking them themselves.
Diabetics, cardiac patients, HIV patients, MS patients....etc....all take medications. So do I and because of them I am a reasonably happy, healthy, and functional person.
