Do you ever doubt your own emotions?

I have come to the conclusion that I do not trust my emotive responses. For example, if I get really angry at a person, or situation I question if I am being “right” in being angry. Or do I have a right to be angry?

The reason I ask is, if I am confused and this situation warrants anger, then surely I would need to react appropriately. I am not talking “bash them over the head” but more a case of trusting that I am angry for a purpose. Do you ever question your emotions? or not? Also how good are you at putting forward your anger in a constructive way?
