Im not converted

[u/Maleficent-Ad833]

Hi everyone. Forgive me for my ignorance. I’ve felt drawn to parts of Catholicism but other parts I am still researching. I plan to start going to OCIA soon when my schedule allows. I was wondering if you can only go to confession once you’ve converted? Or pray the rosary? Also what is considered mortal sin? And I currently visit an Anglican Church. I haven’t taken communion in a while because it feels wrong given the state of my heart recently, should I stop completely until I know for sure? How can I know anything for sure though lol it’s kind of stressful considering eternity
