I second the advice to not get baptized unless that is YOUR choice. Getting baptized makes things a whole lot more difficult if you in the end decide that you want to leave.
JWFacts, as everyone else has mentioned is a wealth of information, and is honestly the main reason that I woke up, but there are also a lot of youtube channels that you can go to that have information in a easy to understand way, with their own personal experiences and struggles. I'd recommend EXJW Critical Thinker, JWStruggle, & John Cedars. Those folk were the main ones who helped me, but there are TONS more out there.
This is a really confusing time for sure, and you are in a tight spot because at 13, they might not listen, simply because of your age. Hell - I know if I learned this at your age my parents would have punished me, then sent me off to my grandparents so I could get an ear-full more.
But right now, the most important thing for you is to keep learning, don't stop researching, but also don't try to start a fight with your family over differing viewpoints. For the time being you might have to go with the flow, but learning the truth early will pay off in the long run.
