I have felt like screaming sometimes myself. It may seem lame, I just left them behind. My family has always called me Michelle but they have problems with pronouns, I don't spend much time around them anymore. I changed jobs and moved. I am just another woman now and everyone I know and everyone I meet treats me that way, I can't go back to that crap from people who have known me forever.
It's been a very long time since I have lashed out so I am not sure that I can help you there.
My way of dealing with people who got the memo and didn't make an effort to change is probably not the best but honestly, I don't need them, we were not close. That is not normal I am sure.
It really is patience. Patience with yourself as much as them. We can't let ourselves be monsters but we can try not to be too hard on ourselves when we do lose it. Somehow, for whatever reason, it makes it easier next time not to freak out on someone.
