Potato, you are getting some great advice already. Please notice something: you are making a choice already when you go to anti-Catholic sources for input about faith.
That is an important choice you are making. It is clear to me and to those who have already posted, that you are not well informed about the content of your faith.
Faith means two things: The content of the faith, and the act of faith. The content is the propositions our minds considers, such as God is Three in One. That is a proposition we can think about, and as Catholics we accept it as true. The Act of Faith is the movement of our will towards such ideas as towards goods. The will moves towards these things to embrace them as desireable and dear, as loved. We both know AND love our faith.
As faithful people we know what we believe, and we love what we believe.
The more you know, the more you will love your faith, and the happier you will be as a human being. You will also, as a side benefit, be more confident in explaining your faith to those who sadly do not believe. Most of that unbelief starts in misunderstandings–so don’t you start there too!
No matter your worldly goods, you are already rich. For you are born into the richest heritage in the world, for you are a child of the Catholic Church and as such you inherit all her rich 2,000 year old wisdom and goodness, and her 2,000 year old service to her Lord. Your parents, I presume, gave you this inheritance, and it is your place now to treasure these riches, explore them, and keep them unharmed to hand on in your turn.
