Sent home by my friends for having epilepsy

A couple weeks ago, my friends were having a get together for their band’s first showing for their music. I was invited to attend by them in the first place but when I showed up, the friend whose house it was being held at left to go talk to his family and then a little later came back and told me to come with him, so I did and didn’t think anything of it and when I came upstairs I was told an Uber was coming to pick me up and that my being there was making others uncomfortable, I tried explaining that it wasn’t an issue and I am on new medication and that I hadn’t had a seizure in over a week, but they still said that the Uber was on the way and I would have to leave. They tried saying they were sorry but I was just not in the mood after hearing all that they had to say. I went home and just played video games for the rest of the night, I just woke up from another seizure a little bit ago and I still don’t know how to feel about that day, they told me things like “what if you have a seizure during our concert? Then the night would be ruined for everyone and we would have to stop the show. And there are going to be flashing lights.” I tried explaining that flashing lights aren’t an issue for me and they aren’t a trigger but they wouldn’t listen, so I just stood there in silence with my head down and asked when’s the Uber getting here and left when it showed up.
