I am sorry you have to go through this, hope you feel better after you talked here Having unsupportive parents must be hard too. Our own parents shouldn’t mocking us, no matter how “weird” we are. If your parents mocked you then shame on them.

For me anything you said doesn’t sound stupid at all, and you are obviously not stupid, you are still in school but you understand Tolstoy and Kafka. As for your writing is not as good as them, first I say that those men you mentioned set the bar high for everyone. I am an aspiring writer and reading their books makes me feel like I should only write for a cheap celebrity gossip magazine, I have no talent at all infront of those great men. Second, I believe you know that Tolstoy’s teachers described him as "both unable and unwilling to learn” when he was still in school. If he gave up back then, we wouldn’t hear about his name now. Keep on reading, keep on writing, keep on doing things that you like even though it’s only work as distraction, and please keep on living.
