My job has been really rough for me this year as well. Extremely busy in a high pressure global environment.

Part of the cerebral benefit of Depression is that I looked into what I want to do as a future Career a LOT. However, part of the difficulty is that you feel like you'll never get out.

I think for me what helps right now is that I focus on what my priorities are, and keep that confined to three things at a time.

Right now that's:
1) Meditation, I do this before work and on my lunch breaks I go for a walk and meditate by a pond. This is tremendously helpful.
2) Exercise. I try to either go on a 30 minute walk or do Yoga along with some hikes on the weekend. Getting active is critical I think.
3) Journaling. At the end of the day I journal about whatever I think is pertinent, whether that's work, therapy, health, relationships, etc.

Perhaps focusing on improving your overall vitality will have beneficial consequences for you at work? It does for me, but I also try to practice a TON of compassion towards myself, as I do fail and fall short of my own standards. That's okay.

I hope you find something you love, but more importantly I hope that you come to love life again and become a productive person out of an earned vitality.
