Freaking tf out. Please track/ send vibes/tips

EDIT: SADLY I'M CANCELING

Im on UA1421, ORD-FLL. I was supposed to leave today but I freaked out. Before that I was supposed to go to cancun but was very overwhelmed by everything, I didn't want to go international and I didn't want to fly over water. This will be my first flight in 5 years. I really want to to explore but I developed some agoraphobia tendencies during covid. Recent events are making it all worse. I need to get on this flight but I'm legitimately terrified given everything.

My flight leaves 7am central.

Thanks
