I booked a flight to another state. It’s only a two hour flight, but I’m still nervous to go!

My friend recently just moved there by car and she misses me and wants me to see her. I really do want to go, but I get scared thinking about being away and being on a plane. It’s been emotionally exhausting ever since I booked the flight. First I’m excited then suddenly I’m struck with so much anxiety I start shaking and then the next day I’m excited again and then the day after that I’m shaking! Aaah! I dont know what to do!? Should I cancel or should I go!? Has anyone flown recently!?
