回複：可能是小事一樁，怎麽覺的那麽鬱悶

You could talk to your manager about your willing for taking more duties when you get chances.

But it is not a good time to make any complains against anybody right now. Be positive and keep a good relationship with your manager and boss via proper communication gradually.

Do not argue with your coworks even they treat unfairly if you are not strong right now. Try to keep your duties under your control.
