My best friend convinced me to go watch a movie with her friends and I feel awful about it. I hate socializing and I dont know why. Im not even a full NEET, I go to uni, I have one close friend. Why do I still feel like this? How do I stop being like this?

Got manipulated by my best friend into going to the movies with some of her friends and I don't even want to go because I have to shower, get dressed, and comb my hair.
