Damn dude. Tbh, I came in here with the intention of cracking a couple jokes and keeping it chill, but your post made me feel bad. I wish I could help you, under my old boss, I generally hated going to work every day, and every day I kept looking for something that would give me the opportunity to get out of there. Then he got fired, I get along great with my new boss, got promoted two weeks ago, and am now generally happy with where I'm at. Long story short, a simple change can make a world of difference.

As far as your situation goes, it sounds work related, it also sounds like since you are stuck in your routine, which isn't helping. I would suggest possibly breaking the routine, talking to your boss about it and seeing if maybe he could let you take a little time off to figure out how to get out of this funk, and thirdly seeing a therapist. PTSD can lead to worse things if ignored, and if you don't have the money/don't want to see a therapist, maybe just try opening up and talking to someone about it, someone you are comfortable with, who you trust and has good intentions, aka not a friend who would just laugh and tell you to have a drink and relax. I know there are people on this site who have a lot more wisdom and experience than I, so I hope myself or someone else here is able to help you figure out the solution to your problem.
