Dealing with anxiety by being angry and mad

it always feels easier to deal with than crying although I know its unhealthy, in times like this it feels like I'm regressing to protect myself because I haven't seen a therapist in 3 years.

I feel irrationally angry right now for having gotten woken up by my boyfriend's alarm this morning and when I ask what it was for his only reply was "you should know we talked about it yesterday" No I wouldn't ask if I did, I just woke up??? Apparently he was hanging out with a friend on discord and I love how I have to keep track of his plans for him.
and now he's basically yelling into the mic to talk to his friend so I have to blast music to drown it out.
I tried joining in one of their conversations only for my bf to completely shut me down
I had the option to join their call yesterday, but last time I joined a call I was more anxious and didn't even talk so it felt pointless, his friend only even talks to him and hardly acknowledges me so I'm not missed.
I wanted to relax more today before everyone got home, and we had to continue apartment hunting but I guess not.

I know these sound really fucking petty, and it doesn't help that 7 cups doesn't have anger management
dunno what else to do but vent

anyone else deal with anxiety by getting mad?
