Hello, and welcome to the forums ^^ I'm Amethyst the Maine Coon cat
Like everyone else said, don't be hard on yourself for liking a certain fandom. I know it sounds corny, but as long as you aren't harming anyone you should do what makes you happy. If you can't be a furry in real, there's lots of nice people to meet and talk to on here. I'm still fairly new myself, but I'd be glad to help if I can
Also, I don't know your parents and maybe I'm being nosy, but do you know if your parents really will get angry if they find out, and if so why? I don't know if maybe they'd be responsive to a discussion on what exactly the furry fandom is. Sorry if I'm being rude :p
