A sure sign of capital deprevation. Use more caps in your sentences and all will be restored.
But seriously, it's great that your beliefs are being challenged. It sounds like you're fairly young, I'd guess mid to late teens, and that's a wonderful time to be exploring who you are and what you believe.
is there anyone who can testify much about the church?
Sure, there are several LDS members here, particularly LDSDude. But I hope you'll use this time to explore beyond just LDS.
May I suggest that you take a sabbatical? Take some time and explore some of the other paths that have been taken over the ages. You can start with some of the Eastern Philosophies.
Here's a good place to start.
Don't neglect some of the influence that led to Christianity such as the Greek Philosophers. And also explore the Judaic and Islamic parts of the family.
Take your time, there's a whole life ahead of you, and much can be gained no matter where you end up. Explore Atheism, Agnosticism, the various branches of the Christian faith, Hindu and Buddhist, Confucious and Mencius. Study them all. You'll come to the path that works for you.
