I don't want to make assumptions but your reactions sound very similar to mine, and I have been diagnosed with CPTSD due to childhood trauma, yelling/anger being a huge component of the trauma. Because of it, I also get very shaky and have a difficult time talking to people who are aggressive/angry or even just mildly rude/confrontational. I also have a hard time keeping my cool and sucking up to people who are rude (the latte model often feels demeaning). I remember recently a lady came in for a refresher with light ice and claimed her drink didn't seem like it had light ice. I had made the drink for her, and specifically used a tall scoop in a venti, so it was *definitely* light ice. I was so irritated by her complaining that I didn't offer a remake, I just assured her it was light ice as I had made it myself. I didn't realize until after she left that I had handled that "wrong" according to sbux standards and I felt kinda bad about it. But I digress.
As far as tips for dealing with it go, I think the only thing you can really do is try to not take customers too seriously. I know it's easier said than done but it's the only way. Also, sometimes being overly polite in response to rudeness is more of a slap in the face to them than matching their rudeness. However if they are overly rude and aggressive, let your SSV handle them. You don't have to take abuse.
All of that said, if you haven't already, I would encourage you to look deeper into why you have these reactions to confrontations from customers. To me, it sounds like you are experiencing textbook symptoms of being triggered, specifically with feeling shaky and like your throat closed up. Again, I don't want to make assumptions so it's up to you to examine if there is anything to what I'm saying. If it is bothering you this much, I'm saying this kindly—this might not be the job for you. I had to leave my last job because I was constantly triggered by my angry boss and it was the best decision could've made for myself.
