It can certainly be helpful to keeping a cool head when facing difficult situations.
I'm sorry to know that you got fired from being bullied. I can only imagine how things must have escalated. It can be quite tricky dealing wtih toxic people in the workplace. I was lucky that when faced with a particular toxic person, my boss served as a go-between for me and that person who was a team lead. He would have individual meetings with each of us and convey our thoughts and feelings diplomatically to each other while the other was not present. This allowed for several weeks to go by with such meetings a couple of times here and there, and eventually, we came to a mutual agreement and we were able to work together respectfully.
