how do i stop being housebound

i'm desperate and hoping some of y'all may have some wisdom.

i'm 23 and i've never experienced agoraphobia prior to this summer. i've always had anxiety/panic attacks/emetephobia, but never feared leaving the house. to make a long story short, i was 1,000+ miles away from home this summer stuck in the middle of a crowded bar, overheated, and started dry heaving (whether it was from anxiety or the heat, i don't know). i was mortified (was with a huge group of my boyfriend's friends) and my boyfriend and i had to uber back to our hotel. i never really recovered. i had about 10 more gagging fits in the coming weeks - once an hour from home driving alone on the highway (this was horrible, i cried uncontrollably, turned around and went home, but it happened the whole way home), another time at a doctor's appointment, in the car with other people driving, at the ER, etc. as you can guess, it turned into agoraphobia. the gagging fits wouldn't have been a big deal if gagging wasn't one of my biggest fears (hand in hand with throwing up).

it's been 6 months since this all started, 5 since i last had a gagging fit. however, i've lived in constant fear every day since. i've stopped being able to give presentations, i've stopped going to bars, i struggle to go in public at all (but manage grocery shopping/shopping/school, with panic attacks). i work in healthcare and talk to patients all day long, but i had to start working remotely. any time i talk to someone that isn't my parents, my throat tightness up like i'm going to gag (so all day during work, during classes, etc). it happens as soon as i walk into a public place. i am so miserable and i am so done living life like this.

one year ago today, i was able to fly across the country alone, drive 16+ hours in one shot completely by myself, live 1,000+ miles from home. concerts, clubs, bars, weddings. i loved life and i was actually living.

i'm in therapy 2x/week. i've tried medication. nothing has kicked this. i'm supposed to move 16 hours away in 4 months. i'm debating skipping my grad school graduation ceremony over this.

i would greatly appreciate any wisdom or advice. thanks so much ❤️
