I'm sorry to hear you had such a bad experience with the things you should've been able to love doing the most.
My parents haven't actively ridiculed my interests and hobbies, fortunate to say. But neither have they been interested whatsoever. A long time back, before I got SSI payments, my dad one day wanted me to do something like clean something, I said I didn't have time because that was the time I usually wrote, and he said there were more important things than my writing, since my writing wasn't bringing in money.
My mother's and other relatives' interest in my writing has never gone beyond "What do you plan to DO with it? Are you going to try to get published?" ("Is anyone even reading it?" my mother asked when I mentioned I post it online. I took it as an insult, even though it's basically true. What she really meant was, I shouldn't post it online, I should get it published before somebody stole it. That didn't help me feel much better.) None of them ever want to read it. They just try to tell me to get published. Never stopping to think, maybe one big reason I don't even try is because nobody reads it, not even them! Even if I were published I know they would not read my work.
My mother once said one big reason she wouldn't read my stuff is because of all the weird fantasy names.
None of them know about my adult writing and I hope they never do.
I'm really not into my parents' interests, e. g., my mother's beadwork, but I go out of my way to encourage her with it, whenever she shows it off to me I compliment how beautiful it is, and ask what she's working on, and offer suggestions for color choices, and encouragement when she feels down or frustrated about a piece, etc....you'd think I could get the same in return. Instead, I just feel terribly embarrassed and ashamed of showing off any of my stuff to any family, now, so even if they were to ask, I'd just brush it off, deflect the request and move on.
We recently stayed with my brother's family. His little girl is so outgoing. She'd put on shows for us, dance and sing, and show off her work, I was so envious because I used to be that little girl. For a brief time. Until my parents kept getting irritated whenever I'd try to share things with them ("Go read to the cat!" I'd be told; plus the main reason I started writing seriously was because my dad wanted me to stop bothering him!), and I just learned to keep it all to myself because nobody wants to see/hear/read it.
I hate to admit that a spiteful part of me was thinking, as I watched my niece perform, "Better enjoy it now, several years from now nobody'll care about what you do anymore." But I've seen how things go in this family; she will continue to be loved and appreciated, because she has actual talents that others can appreciate, whereas I was born with none. I'm the only one in the family like me.
So I know those feelings...yes. If our own parents can't appreciate what we do, how can we believe anyone else would?
