Welcome to the forum, Chrissy. I hope that you will become an active member of OC.net and we all look forward to helping you with your journey.
I, too, was raised Lutheran, confirmed in that tradition and very active up until I decided that I should become Catholic. During my college and grad school days, I did not become Catholic simply because the Catholicism that I witnessed was not the Catholicism of history; it was a watered down and near Protestant version and that is NOT what I wanted. After getting my job up here in Omaha, I decided one day to simply go to an Orthodox Vespers. I'd never been to one before and I just wanted to see one "for the heck of it." Anyway, I went and I never stopped going and was chrismated just under a year later. After that time, I never, ever had any doubts that this is where I was meant to be. There was some apprehension, to be sure, especially since I knew my parents were hostile to the idea of me becoming Catholic so how would they take this? Would I end up missing Lutheranism? All my concerns proved unjustified. My parents are OK with it and I don't miss Lutheranism at all especially since, imho, what I left really wasn't Lutheranism, but the Baptist faith with some Liturgy. Maybe I was fortunate that the demons' assault on me was not as it has been on you. The key is to make sure you are not doing this alone. Reading books and going to Liturgy and talking with the parish priest are all well and good and necessary for this step in your journey. But you need support and help. I was very fortunate that the first person who reached out to me at the church was a tonsured reader and he frequently called me and invited me out with his family to talk with me and help me on the way. Eventually, this person became my godfather and he is now a priest.
I hope that there is someone there among the laity that can be there to help you along the way as well. Just as when you go to the gym, it helps to have a training partner, so it helps to have a partner with this journey--someone to pray for and with you as well as just being your friend in the process. Hopefully someone will seek you out.
Good luck with everything and, again, welcome.
