Is it mental health issues?

I think something is wrong with me I can’t talk in public, I can’t answer all the questions, the problem is my mind went full blank my hands shaking and I can’t think of anything even though I tried to calm down and it was an easy question. I failed my test because of this..

It’s not always like that, even I surprised not understanding why did I turn this way. I haven’t done some public speaking in 2 years.. is it because of that? or because I’m under this crazy boomer for a few months? Because I’m really truly scared of him. He makes every small mistake like some paper clips position a problem. I know I should just ignore him but I’m stuck all day with him literally fully all day. Its a very small team

People hate him and dont take him seriously I think that’s why he taking his issues to someone under him. And there’s two guy quitting because of him but they write down a different reason ( of course) one of them have mental issues. I’m so scared I might have developed mental issues as well
