Any advice?

[Roxy904]

So, my mom is fairly Catholic, and my dad is... some sort of strange Protestant thing. (I'm not really sure.) I'm a 13-year-old girl, and I first started actually questioning my religion (Catholic) at around 9-10 when I started reading more books, and exposing myself to other opinion and thoughts. I really loved reading and thinking about what I read. I'm able to read at a fairly high level for my age, and reading opened my eyes. I matured and felt more and more like a fool when I had to act religious. (I go to a Catholic school and I have to go to Mass once or twice a week.) The more I thought, the more I disbelieved that a God had impregnated a virgin with himself who was also his son; and that we should eat his body and blood for redemption. To use an expression from the book 1984, I basically had to doublethink. I have been dropping hints to my mom about my non-Catholism; I have get Confirmed, and I argued with her briefly about this before agreeing to get Confirmed, because I am under her roof and her jurisdiction. However, I wasn't fully agnostic then, as I am now. I have to choose a high school soon, and I was discussing this with her, when I told her I didn't believe in being Catholic, etc. She became upset and told me, well, basically that she was disappointed that I had dismissed what she had tried to instill in me. I told her that I could be a good person without religion, and the discussion continued on for a bit. (She is a scientist, which confuses me as to how she can be intelligent, but believe such crap.) I could see that she was hurt by this, and she genuinely is a very good mother. I don't want to insult my mom or her beliefs, but I could tell she felt insulted; she felt like I was telling her that her beliefs and the beliefs she tried to instill in me were wrong. I hate that she feels like this. Most people don't want to hurt their mother. Any advice for dealing with her? Any advice for getting through the school year, trying to pray to a God that I don't believe in? Any general advice for high school, which may or may not be Catholic?Thanks for taking the time to read this long post.
