"And I hope to God I figure what's wrong..."

I feel like I am failing at everything in life. Not every aspect of life, I have many good things to be thankful for, but I can't get my career together. I need to go back to work but I have a lot of anxiety about it. I'm notoriously flakey but I am getting better. I lose interest quickly and space out. My skills could be improved upon greatly. Sometimes, I feel like I am not in the right field but I love it so much. I'm torn, do I keep trying or just give up?
