Don’t think too much about a vocation to the religious life at this present time. Firstly, you need to convert because you believe in ALL that the Catholic Church teaches, and not because it is easier to become a priest.
Secondly, I would strongly advise you to deepen in your spiritual life as a lay person before you even consider your vocation. I would leave it for a couple of years so that you can truly decide which Church you are called to serve.
This is a massive, massive decision. Take baby steps first and do a lot of praying. Sometimes you just have to stop thinking and let God take control. Give him the wheel, and let him steer your life.
Pray the Rosary for guidance and discernment.
