Yep. Sounds like depression to me.
I think you need to see a specialist again. Our bodies are changing all the time and new treatments are being discovered all the time as well so there is still a lot to be hopeful about. Depression is such a sneaky disease and when you are in the throes of it everything becomes complicated and huge. You feel powerless and overwhelmed. Self loathing and shame are what comes naturally. For me medication helped me to manage my depression and all the things I thought were so complicated became simpler when I could think more clearly. I'd definitely try again.
Hang on to your job. They are precious these days.
