I don't know if he's tired or being a jerk

I spent last night with my boyfriend. I woke up at exactly 8 in the morning having a full on asthma attack and I have nothing. I'm pretty sure it's because his uncle smokes. I'm like dying right, I can't even talk because I can't breathe and I can't get ahold of my mom which I am desperately trying to do so I wake him up and tell him to take me home and he gets THE worst attitude with me. That's the wrong thing to do when someone's having an asthma attack, i don't care about your damn feelings I just want my oxygen. He gets so mean with me I basically cancel the plans I have with him inlcuding the movie we were supposed to see. If you're going to treat me like crap over the fact that I CANT BREATHE you can go to a movie by your damn self. Am I being too harsh!?
