I'm sorry you were so devastated! What a horrible thing to have lost something as wonderful as playing music because of such a bewildering experience. This was a terrible loss.
I've never had such an experience. But I'm saddened by what happened to you, because I also had various factors rob me of being a musician at various times when I was a kid. One of them was when I was in 6th grade and couldn't practice my saxophone, which I was just learning to play that year, without having to hear my sister shrieking and pleading with my mother, saying things like, "Does she have to play?" I'll grant that no new musician sounds great. But my teacher said I was one of the best beginning band students that year, so how bad could I really have been? After all the hounding and harassment, even though I was playing up in my room, with the door shut, my parents couldn't get me to practice anymore. I still loved the instrument and the things we got to play, but I was too distressed about being heard to be able to do it anymore. I went on the play in 7th and 8th grade, but almost exclusively in band class and performances, where I could blend in and hide amongst the other instruments, never at lessons and very rarely at home, where I would stand out and be heard alone. After 8th grade, I never played my saxophone again. I was really hurt over this.
My sister had sensory issues nobody knew she had, let alone understood, so I feel some sympathy for her. But she was older than I and could've left to visit friends, go for a walk, or hang out at the nearby plaza or something. She wasn't stuck at home. Furthermore, when my younger sister took up violin, nobody was allowed to complain, even though she practiced in the middle of the living room at first. So, even though my sister may truly have been in pain, there was no reason for my mother to allow me to be put in pain as well, and to have my musical development stunted, by letting my sister go on at such high volume, for so long, whenever I played.
