This all makes me so sad. I am an ex professional opera singer, and so would like to add my story to this (although I did encourage some time ago on the thread). I have one of those (trained) voices that will hit the back of an auditorium, over the top of an orchestra.
I have three children, and I used to drive them bonkers. I would sing around the house, especially when learning something new,, and would make things up in my vocal exchange, 'haha! you are just so.... naughty!' Aka recitative. It isn't good for the voice to shout. They used to tell me to shut (the fuck) up. I'd sing the reprimand..
A couple of years ago. my son arrived home in the early hours. He'd spent lots of time with one of my ex students. She said to him, simply 'your mum used to ope her mouth to sing, and the sun came out. It was the most beautiful sound I'd ever heard'. He was incandescent. He apologised to me for telling me to shut up. Profusely.
He apologised for his years of telling me to shut (the fuck) up. he also told me that he thought that Opera was the finest form of music. He was pissed, obvs! But there was truth and acceptance.
I'm not telling you this because you're an opera diva, or choir diva, or anything else. I'm just asking you, again, to do your own thing. As for joining a choir - tops idea. Also find a qualified singing teacher who can work with you on technique. Never, ever doubt your ability.
I expect that I'll be slated for this for blowing my own trumpet. It's all true though, so I wanted to share it.
In the meantime. Never stop singing. And if anyone tries to stop you, Poke them in the eye with a blunt stick.
