Stressful trip trauma/anxiety/derealization?

So I went on a trip across the states via an airplane, I’ve never ever had problems flying in my entire life but this time was different. I went in completely sleep deprived and had to go through about 13 hours worth of traveling.

I had one of the worst panic attacks of my entire life on the plane and continued having anxiety/dissociation spirals during the entire trip. I even had panic attacks on the flights back home as well.

I thought when I got home everything would be normal but now I’m suffering with the exact same feelings as being on the trip and on the plane.

The day after I got home I went out and had a lovely day with my girlfriend drinking wine and stuff like that but when night came around and I guess the alcohol had worn off I had a major major major panic attack that lasted hours and hours until I finally was able to sleep at 5am. It literally felt like nothing was real and I was either dying or losing my mind. Nothing looked right and if anyone is familiar with dissociative drugs it was like that but with none of the good parts and all the bad.

It was only a few days ago since this happened but it’s been persistent multiple anxiety attacks daily, accompanied by that weird background feeling of dissociation like everything and the world around me just feels different like something has changed or that I have changed and feel different.

My psych prescribed me lorazepam for the panic which honestly just made the dissociation worse but kinda helped the anxiety but not really tbh??? When typically benzos help me immensely.

She also put my on buspar which I am highly reluctant to try for whatever reason.

Please I really need some help. I’ve never felt desperate like this. I have a really had semester of class and work coming up and it’s been making me extremely depressed.
