Your first reply to her is unacceptable. She gave you a task to do, and you talked back and put it back on her. Then you gave her an excuse blaming it on someone who isn't there. If you cannot work because of emotional turmoil then you should not be at work at all. Explain to me why you cannot physically fill the sauces up because of the GM not saying hello to you? If your moods rely so heavily on other people simply saying hello to you, and you physically cannot work because of that, then you need to look for additional support because you should not be working at all.

I don't think this had anything to do with the GM. I think you didn't want to listen to the trainee manager because of all the backstory you gave and that you don't like her. So you gave her an attitude and blamed it on the old GM.

Does it bother you at all that you put HIS career in jeopardy when you keep acting like he actually did something to you and telling other people he "put you through hell' when all he did was not talk to you and you have no relationship with him to entitle you to any of his attention? You could get this man in trouble and cause him a lot of harm with these accusations. He did not put you through hell. Your infatuation is putting you through hell.
