Congratulations dude!
Some people may not understand how debilitating anxiety can be. Good for you for overcoming your anxiety and going to a theater. I hope you had a nice time. π
I have mixed feelings about going to the theater these days because it's so relaxing and nice to watch stuff at home on my nice OLED TV (plus drinks and snacks are cheaper π). But it's certainly a good experience to go to a theater for the first time.
And now it'll be much easier for you to go again the in future. Or to go to other kinds of theater performances, like plays, musicals, opera, concerts or whatever. π
