I was put on a heavy dosage of anti-depressants about three years ago when I was seventeen. The drug was meant for adults and I felt worst when I was taking them than I ever had in my life.
The ones closest to me who knew that I was taking pills seemed to base all of my emotions from that point on effects from NOT taking my medicine. As in a day where I was feeling upset about something completely rational, they would mumble in a pitying voice, "Did you take your medicine today?". Maybe it's my annoyance with the stereotypes surrounding depressed people, but it seems that when you begin to take medication, you are branded as irrational. To me there is NOTHING worse than this.
My zombie effect hit in around two months. Although I don't like to show my emotions as it is, it was a whole other thing completely when I just didn't care about anything anymore. The people closest to me didn't matter. Currents events didn't bother me. My passions simply became things I did because I was expected to. That's when I decided it wasn't worth it. I was losing the things most important to me because I couldn't feel. I wasn't depressed, but I sure as hell wasn't happy.
I took myself off them with the help of a close friend and picked up a new sport which I obsessively did whenever I felt sad or upset. After such a long workout, sometimes ranging from three to six hours of intense working out, I would forget why I was upset to begin with. No more zombie feeling, thank Hayzeus.
