I concur with JJ299. Avoid excessive analysis. Your understanding is sufficient to proceed with this; simply proceed and rely on the medical professionals, nurses, and patients to address any other inquiries you may have. You are undergoing this at the Paley Institute, so you are in excellent care. You will encounter other individuals there who will support you throughout, as long as you are candid with them. Have confidence in your ability to see this through at this stage. Regardless of the challenges, keep in mind that if you remain resilient, you will emerge even happier in 4-7 months.
