Having emotions is unavoidable and of course you are 100% entitled to all of your emotions.

That said, our perceptions (feeling deliberately ignored, for example) drive our behavior. We are expected to control our emotional responses, not meaning to deny the emotions or push them away but to let them be heard or understanding our perceptions, so that we can see if they accurately reflect the reality.

We can learn to speak up and ask the other person if tgey are unable to hear us, if this is not a convenient time to talk together, if they understand what we are saying, etc. Therapy helps very much with those things.
