I fully support your decisition to become Catholic. I highly recommend you watch some Sensus Fidelium on YouTube for strong traditional Catholic content (hard to find these days for young men like me who seek real spiritual guidance that is not new age garbage). Also, there is a YouTube channel called "Adoration of the Cross" with old chantics.
1- Go to mass every Sunday
2- Kneel to receive the Holy Communion, sacred body and Flesh of our Lord Jesus Christ
3- Confess weekly if U can
Dude I cannot tell you how this last 3 things have changed my live. I hope you can find some solace knowing the fact that there is someone praying for you, and asking God to give you strength to confront this World invaded sin.
You need to iniatiate yourself on the Sacraments with the closest Priest, I am not very aware on how to convert as an adult.

You have made the right decition. Our Holy Church might be full of Marxist, pedophiles and New agers heretics, but those are human components that failed. We must all, every single one of us the decent Catholics left on the world, work together to keep the Church as holy and Sacred as the pope Saint John II wanted it.
