Glad that you feel supported, of course it's a shock. But it sounds like your medical team have been thorough and are taking the right actions. Reactions to drugs and treatment vary a lot, and it's hard to know how you will react until you start. Main thing is to ask questions (if you have someone to be with you in appointments and take notes, it's a help), try and take one step at a time as your imagination may take you places you may never need to go, and remember lots of us get through this. Very best wishes.
