First date?? Help! 😭

Alright I’ve known this guy for like a year and a half and he’s one of my best friends. I know for a fact we’ve liked each other for about a year of that and we both are aware of it, but sort of tiptoeing around it (we both have anxiety disorders lol). Anyway, I finally mustered up the courage to ask him to see a movie with me tonight and he said yes. We never specified it was a date but it’s our first time, as two people who like each other, going out alone to see a movie by ourselves. I mean idk if I should be calling it a date but based on the circumstances, it definitely feels like one. I am ridiculously nervous. (Remember that anxiety disorder I mentioned? 😂) so I just need a little support and advice on how to handle this. Thanks!
