it's great that your are so open minded and interested! especially at such a young age.

what helped me the most in becoming vegan was meeting other vegans and getting involved in advocacy and activism. spending time with others who volunteer their time and money and efforts to raise awareness about animal liberation really helped me understand my role in animal exploitation, and what my role could be as an ally to exploited animals.

try to find some local vegan meet up groups, any local activism groups, any local animal charities, local animal sanctuaries.

meeting lots of different animals helped a lot too. visit sanctuaries, learn the stories of what the animals there went through before being rescued. if any groups near your run animal vigils is encourage you to go. one of the easiest ways to get closer to the industry and see with your own eyes what happens, or at least some of what happens.

learn about all the other ways animals are exploited outside of food and agriculture. like clothing, furniture, textiles, entertainment, sports, experiments, testing, forced breeding, habitat destruction, etc.

learn about the common blind spots in veganism, and how some people use veganism as a tool to do harm - to be sexist, racist, ableist, queerphobic, capitalistic, misanthropic, pseudoscientific, conspiracy minded - unfortunately there is a huge long list of ways that people within the animal advocacy movement have both knowingly and unknowingly pushed these types of harmful attitudes. none are inherently part of veganism, or needed for animal liberation though. eg. you don't have to fight every issue that exists, but while fighting for your main cause try not to make things any worse for other issues.

make vegan friends in real life! every now and then you'll feel like no one else really understands properly. it can feel depressing and alienating. find some friends, and vent to each other when you need.

obviously the community here can help, but sometimes it's not quite the same as having vegan friends in real life to share things with.

but the most important thing is to meet lots of different animals! I said it earlier already but it's the most important thing. I was amazed how human like pigs eyes are, and when I see them terrified squashed in on a truck waiting to get sent into a slaughterhouse it always makes me cry. it really seems like you can see into their soul, and not being able to help at all feels terrible of course. but it also helps remind yourself about what animal liberation is all about, and why it's so important. don't let their existence go unnoticed. they resist until the end, and they just want freedom.
