On anger

I find it difficult to properly express my anger. I’m a girl who’s short and fat so most people laugh when I express anger (when I say “express anger” I mean “saying that I am angry or disapprove or disagree”) as it seems powerless and childish. So I basically eliminated my anger (it’s not good to be angry anyway so I worked hard on temper breathing thinking before you speak etc) and it worked out fine.

But I’ve recently gotten a leadership position in my college and I’ve found myself doing the bulk of the work. I always try to make everyone else do their fair share but mostly I have to do everything. I do want to properly express my disapproval and anger when someone doesn’t do something or does it wrong, I want to have boundaries but I’m not sure how to go about doing this. I basically don’t feel anger any more but I need to somehow keep everyone in line – any tips?
