Boyfriend can’t handle my anxiety

I’m 17. Been dating my bf for 2 years. I’ve had anxiety relating to my health for years. I always think something is wrong w me or make a big deal out of something small I feel. Anyways my anxiety got really bad a few weeks ago to the point it was hard to live my daily life. I feel better now and I’m back to normal but I get really nervous in situations where I feel like I can’t easily get out of them. Yesterday my bf wanted to go on a double date w his friend and us and I was scared to go. I didnt wanna have a panic attack infront of them. My bf got mad at me and really annoyed. He thinks I’m crazy for the anxiety I have and kept calling me annoying. I ended up going to make him happy and luckily I was okay. Idk I just want support from him?
