Why am I like this :(

I’ve been REALLY SUPER anxious these past days due from graduating highschool getting my grades up and me and my mom and my step dad kept smoking around me in a truck really close and it makes me anxious and we went to go check out where I’m going to have my grad party and I blurred out of my mouth “MOM WE NEED TO LEAVE IM HAVING A PANIC ATTACK” I am diagnosed with this disorder and for some reason I get triggered by open places like big fields and etc and everything feels unreal please give me advice :((
