gundown. Glad you found PC. I'm sorry you are having such a bad time with depression. Me, too. I can empathize with you. I, too, have been on so many SSRIs I've lost count. I would suggest that you see a psychatrist, though. They are more capable of prescribing other medications that work on depression other than just SSRIs. There are some meds that used with SSRIs that really help. There are a lot of combinations.
I know this because I've tried many of them. I've just had mine changed again and am hoping for the best. I'm bipolar but it has been nine months stuck in the depressive end.

And ,too depression can make you not feel like doing anything. I don't have any motivation either. So sometimes if you cure the depression you cure the motivational issue.

Good luck to you.
