Una - you will do great, you are strong and ready to get this handled. The only advice I would give is to have your mom (or someone) be the advocate at the hospital and at home who makes sure any drug they give you is the correct one and the correct dosage and check for any counter indications if you're taking multiple drugs. Tell that person to ask questions each time, even if it seems annoying to the nurse or doctor.
Take good care of yourself, watch funny movies afterwards -- laughter aids in healing! (we recently watched Meet the Fockers, yes again, and still laughed through most scene :-)).
I'll be thinking of you and sending healing thoughts your way.
