I showed up at the doctor's during drop-in hours. I was "voluntarily" admitted to the hospital, put on fluoxetin (Prozac), and discharged a few days later. After some months, it became clear Prozac was making me worse. Since my depression is the atypical subtype (low motivation, can become happy by doing things, oversleeping, overeating), they switched me to bupropion (Wellbutrin). That worked.

Doctors (or at least these particular doctors) know their stuff, but I double-check everything on Crazy Meds.
