Hi ,
I completely understand how you are feeling, because while I may not be fully depressed right now, I am seeing so many people I know achieve goals and dreams that I may never be capable of achieving. I do feel behind. People are graduating from masters programs, having kids, or getting married and 70% of my friends are in a long term relationship. I had dreamed of being in the same place as them now, but my disorder has made that impossible. It feels awful to feel this way. It isn't the life I wanted either. I'm sorry you feel this way too. And I'm sorry you're depression is so hard to treat. I would give advice if I had any to make these thoughts easier to handle, but I still am trying to do the same. You aren't alone in them.
