Perhaps you have not seen their bible.. There is a huge difference between a person who does not believe in god and a person who actively believes there is no god. Most of the former usually turn out to be agnostic once you talk to them, and most of the later are very active in their disdain for believers.
Yes, I am in a position to tell you leave your religion. You have no idea how badly you've been brainwashed by it. It is distorting your development if you are worried about "the one" at fifteen years old. I have the perspective to realize how screwed up this is, therefore I am in that position.
I'll tell you what, don't take it from me. Do a little reading on your own.
The God Delusion is always a good read for the beginning of the journey.
You have a great start. At 15, you're going to discover so much more than argues against religion - just give it time. Keep questioning and reading. I'm sure the folks in this sub can recommend some good books for you. Like The God Delusion by Hitchens.

In this book (God delusion) Dawkins answers your question. Moral values should not be derived from the bible, they are developed from human experience.

pakiramdaman mo din kung casual dating lang, go lang, minsan kasi ay gusto lang din ng girl sa inc na ma-experience yung kumawala sa social group na ginagalawan nya, for experience lang.
suggestion ko para sa win-win:
alis kayo both sa catholicism at inc, study humanism at atheism, saka studies/researches tungkol sa gawain ng mga cult groups.
I return passive-aggressive with the same.

Do not worry, gods, hell, ... are all man made. But you are making kind of a hell from your life. For the start I suggest you buy https://www.amazon.com/God-Delusion-Richard-Dawkins-ebook/dp/B003JTHWJQ/ref=sr_1_1 but there are many more good books.
The only good ones I've found Are [Dawkins' The God Delusion](https://www.amazon.com/gp/product/B003JTHWJQ) and [America's Test Kitchen: Pancakes and Waffles](https://www.amazon.com/gp/product/B01N7SLHPQ).
