Stuck in a Sensory Labyrinth: Family tension and overload

My parents and I went last night to a Pasta Karaoke Supper.  It was suppose to start at 6pm.  But it didn't start until 6:30pm  Due to people trailing in until 6;30pm.   I would have liked to get up to sing with the Karaoke part  but Mom said "no because it would cost more money"  and then for main supper part it was a table lottery system.  So we had to wait for our table number (5)  to be called.    Then i got aggited when waiting for dessert and people were doing Karaoke and with people  clapping and the mic's feedback...  it was making me overwhelmed at around 8:15pm and I wanted to go home.   Mom told me to wait.     I already had low spoons before even leaving the house because mom told me to change into more "appropriate" pants and I'm always like "no one is going to be looking at my pants! They will be looking at my face!- this isn't the 1950s!!).   I already had spend a large chunk of time away from my computer 5:30pm-8:45pm (when we got home so we been away for more then 3 hours) and mom threaten to leave me behind on a trip next year or the next time the church has an event like that.      And when I tried to talk to Mom later she told me to "just practice" but that's like telling people like Sara Todd Hammer and Cassidy Huff to "just practice" waiting in line because they're don't qualify for DAs anymore.    to the point I wanted to slam the door (I was going to bed at the time of the talk)   

Walking home after 7pm is out because mom and Dad would be worried about me walking home in the dark but I would only be able to escape to the women's choir room or the sanctuary maybe twice at the most to "reset" without people asking questions.  

It's like in John Green's novels of feeling like a broken vessel stuck in a labyrinth without a way out of the labyrinth.      I might have been able to have a bit more patient had I been able to get up and sing  and not be stuck in my seat. 

Yes I did get to socialize a bit and also got to have 2 cans of pop but otherwise
