I’m alone for the first new years in a long time and I don’t know what to do

I (26F) just got out of a long term relationship and I’m single for the first time in a long time. I’m trying to navigate life on my own and prioritise myself. I don’t have any close friends, just acquaintances, and I don’t really know what to do on my own. It’s hardest thinking about what people do around the holidays and with new years around the corner I have no idea what to do. I want to have fun and enjoy myself but with no friends and newly single I don’t even know what that means. I don’t want to just jump into a new fling or act impulsively just for the sake of it but now I have no idea how to spend my new years. I was thinking I love watching fireworks so I might go see a fireworks display but other than that I’m not sure what else I can do on my own. How are you spending new years?
