I Want to Be a Vegetarian

I've been looking into it and I think I want to be a vegetarian. I love animals and there are tons of pros! I'm already a picky eater so adding one more thing I don't want to eat wouldn't really change much anyway while simultaneously making me healthier. The only problem for me is as a minor I still live with my family and I think if I say anything about wanting to try it they might make fun of me or think I'm doing it because "the Internet brainwashed me" or something. Even if they don't actually think that way about it most of our meals revolve around some sort of meat as the main part of the dish and I feel like I'd make it harder for them. Should I just wait to act on it until I'm old enough to move out?
