Hey,
I used to sing Karaoke twice a week when I lived in the US 12 years ago. since I was a minor I couldnt do it drunk which was hard at first, but I got over my fear eventually and just had fun with it, Believe it or not, doing this actually helped me a lot later in life because I knew how to stay calm and just do things that scared me (like public speaking).
Nowadays I only sing in the car, as a widow with 2 kids I dont get out much anymore
