I didn't personally like the manager in question, but I do believe he was trying to do his job accurately. He attempted to follow the process of things as best he could. He simply did not understand me or attempt to be close to me in any way.

As a result of that, he was unable, I believe, to see the extreme stress I was under despite me telling him I was in the week leading up to what happened.

His huge mistake was to ignore my plea to take the day off to feel better and be able to handle the situation. Had he done so I believe everything that happened could have been avoided.

I do believe the manager is at fault and caused the situation by this, but I don't think it makes him a terrible person or anything. I respect him as trying to do his job.

Boring is not so much what was stressing me; the stress was due to silly things holding up the approval of code that saves the company tens of thousands of dollars per week. I had production ready code that was being delayed by styling complaints. ( white space on blank lines )

Code review that improves code I am all for. Code review that holds up valuable fixes for weeks for silly reasons is not good and makes me feel upset.

I did continue to do the work, and voice my complaints, it just eventually got to the point I couldn't handle the stress, so I talked to my manager to ask how to move forward. He did nothing to really relieve my stress and just ordered me to do it anyway ( which I did; even under all the stress )
