NOW WAIT JUST A MINUTE THERE! You shouldn't give up! After all the hard work you put into your stories and art! You can't just back away now! Believe me I know, I've been working non-stop for the past 4 years(not including breaks, procrastination, and artist block).
Yes what your parents did is total bullshit and total hypocrisy! But you don't need their approval.
Not everyone reads books AFTER movies, There's been plenty of people who would rather prefer books first before movies, or just books and no movies, heck I'd prefer the book version of Bram Stoker's Dracula over the Movie version(too much porn, not enough horror).
Your art is not a joke! I'm sure you can improve, and I'm sure people like your works as well.
What you said about people not giving a shit is not true, not everyone on this planet is like that, I'm pretty sure they're proud, I'm proud of you finishing it! You've accomplished something I couldn't.
And saying no one can help you, you have plenty of people who can help, they care about you as much as their peers!
I had my moments where I feel like giving up because I felt like no one would like my shit, but I just kept pushing it until I got somewhere, especially when I'm bored, hyped, or depressed. If you close up all your accounts and erase all your works now, then your just throwing away all what you've accomplished, you won't be able to get anywhere or get the notoriety you wanted if you give up, just look at the other authors and artists, they've probably felt the same as you but that didn't stop them, and you shouldn't stop either!
