Take a break if at all possible, if not then prioritise saving to be able to take some time off. A month+ would be ideal but anything over 2-3 weeks would be nessesary to disconnect enough to start seeing past the tress. Look into therapy/counciling of some sort. No matter what what the actual problem is, having space to talk and vent about it is important. Judging by your post you've got a lot of thoughts and feelings locked up right now, having a professional to work through it with would be really helpful. None of that is to say it's "your fault" or "your problem", but it might help you to figure out your next move. That may be getting out of the industry and into something else, or it might be finding a new job where the issues aren't as pronounced.
