It's really hard for anyone who hasn't experienced it to understand depression. I live around well educated, aware people and even though they think they a empathetic, I can see that fleeting frustrated, impatient look that crosses their face if I even mention my experience. In my experience PC is the only place I've found to be genuinely understanding. But you know that already, don't you?
I hope you are feeling better about your medication. I plan to stay on mine as long as it takes. I have a terminal illness. It's called depression and anxiety. With the last bout I just about checked out. I couldn't take the intense fear and self loathing. With the right meds I can function pretty well. Try to really get that you have a real, legitimate disease and medication can be part of getting well. I've never had access to therapy but people around here highly recommend it. Some of these people have been coping with depression for decades. They are veterans. You can take their advice.
Do whatever it takes to be happy. You deserve it.
