Same for me
And in addition to the forums, you could also check out the Catholic Answers main website and check out their tracts, and I always recommend their book The Essential Catholic Survival Guide (which contains their online tracts in a particular order). The book is more meant to teach you how to debate with anti-Catholics, but it also helps to understand concepts of Catholic theology.
Also, the Catechism is a great thing to have. You can view the Catechism online on the Vatican website, or on the website for the USCCB. Personally, I’d recommend the USCCB version, since I find it more visually appealing, easier to read, and it has a nice search function.
But feel free to PM me. I am a logic minded person with a degree in Computer Science, so I’m used to figuring out ways to describe hard concepts in a simpler way.
