If you were in circumstances where you could foresee your death, I have to think the priest would go ahead and baptize and confirm you with just minimal, basic instruction, followed by First Communion. I would, that’s all I can say. If by some miracle you were to recover, you could then be formally instructed and go through the experience of deeper spirituality, knowledge, and commitment.
As far as how I would describe myself, I would say “I have found Christ and have accepted him as Lord and Savior, I believe in the teachings of His Church, I worship at Holy Mass, and right now, I am studying and eagerly waiting to be baptized and to be received into the Catholic Church”.
