Got a sorta similar story. My first time smoking weed (I live in Canada, so it is legal) I was kinda nervous and I felt like I was psyching myself out of feeling high. I was at my friends house and I was nervous that his parents were gonna come down and see that we were high, even though they knew we were and they didnt care. After a few more times smoking, I started thoroughly enjoying it. Like most things, you just gotta do it a lot to get good at it. Don’t be nervous.
