Well done @kdeey for contacting your BC Nurse ... sounds like you have a really good one - so keep her number handy as your 'first port of call' when you need support (other than us, of course! xx)
Your daughters will be a great support to them .... if you want them (or your friends) to feel useful & keeping busy, get them to cook up some meals for you to put in the freezer, so it is one less thing you need to think of during & after your treatment xx
Re keeping your buddies 'in the loop' - to keep it less stressful, maybe just send out a monthly email to them - so that you don't have to keep answering the same questions from many people who make contact. Let them know that you may or may not respond to their replies, depending on how you are at the time .... and for them not to worry as that is totally normal.
Agree with @Cath62 - it is a real roller coaster ride & we aren't always in control of our feelings .... I was able to sit with my husband thru ALL his chemo, even in lockdown & it helped him get thru it. xx.
Have you had one of your daughters with you at your appts? A 2nd set of ears (and the physical presence/support) really helps. It is easy to miss bits when you are stressed - so consider recording your appointments as well. xx
take care & all the best with your ongoing treatments xx
