My own brother makes fun of my stuttering

My own brother makes fun of my stuttering I had to ask my older brother a question, and he was in his room, I was in the hallway. He didn't hear me, so I rephrased the question a bit oddly. He asked me to explain to him, and I did. But I paused for about a second or two, because I knew I was going to stutter or mess up the words somehow. He rolled his eyes like he always does when I do that. So I told him that it's hard for me to talk sometimes because I have blocks in my speech, and that I wish I could control it, but I'm not always able to. He then quickly said that the way to solve it is to not think about it, and we continued having our previous conversation. But I'm crying because he doesn't understand. He's made fun of me in the past for my stutter. Even when I try to kindly explain why this attitude is hurtful to me, he deflects. He thinks that I'm too over sensitive, and that if I'm still complaining about it in five years, it means I haven't done sh\*t about it. So he just thinks that a stutter is something I can control. I didn't want to cry about this, but it's so hurtful that my own brother gets annoyed. And yes, it's annoying to be the other person having to listen to a stutter, but why doesn't anyone get that we don't want to be this way?
