I think you oversimplify things, Venus. When I was in a terrible depression I agreed to take Seroquel, which has sedating effects so would be considered by you to be a "downer". I was better within four days. Energetic, happy, etc. It honestly saved me from doing something dumb.

With that said meds can absolutely have adverse and opposite effects. For example on geodon I could not sleep, which my pdoc at the time dismissed because she "had never heard of that". I also cannot take antidepressants as they make me mixed (anxious, irritable, suicidal) within two weeks. Sometimes pdocs dismiss these symptoms as mine did because they are unusual, but if it's causing you great distress you mug advocate for yourself and request something different. But also give yourself some time to adjust.
