Memory blanks

There has been a tremendous amount of stress at work. Poor managament in a nut shell. Experienceing PTSD and anxiety not sleeping this is killing me and I am not sure how long I can last. Lots of job duties being shuffeled around. Never knowing what is what, being put intentionally in very difficult surroundings. Malicious gossip landed me in the radar of powerful people and well ya know what it means. Problem is I think am having black outs at work. I am in therapy. So, I will discuss with them. Meanwhile, I was interviewed about some kind of complaints. I am pretty well liked. Been there a number of years and known to be helpful. The questions in the interview were vague and weird. I honestly had no idea where they were going. Well, finally one small statement reminded me of a very simple conversation nothing really. It was indicated there was more. I had no clue, 2 weeks go by and suddenly today I had a flash back and I think I did something for no reason and I do not know why! Holy cow it is so stupid, not illegal or even a huge deal, but out of charachter for me entirely and a bit mean. I am not sure I did it because it just today popped into my brain! My brain is whirrling with thoughts like You are in Big trouble they will use this (if I actually did it) to fire me. I think I am going crazy. I am scared of this because what if it has happend more than once? what if I am doing stuff, I do not know I am doing? Can stress do that? Senility? I have had a few slightly forgetful moments recently lost my eyeglasses on my head, Put a shirt on witht he v neck in back and did nto realize it! What does one do with work in this case? If I did do what my brain is saying how does one explain this to an employer?
