Kaybo is correct when she says that so many people will want to help and not know what to do. I have literally been in TEARS several times during this healing process, thinking about all of the wonderful ways that friends and acquaintances have helped out/stepped up. I recall one time when the phone rang and I physically could NOT talk so I didn't answer it. The machine went off and I could hear a friend's voice leaving a message to tell me that she had just checked up on my daughter and she was doing well. She had arranged a ride home for her, and everything was organized/sorted out. At the same time, my mom was answering the door, receiving a gift of food that was made for us for dinner that night. It was overwhelming to me how helpful everyone was.
I have a hard time with help too, but knew I would need it this time. So when people offered ahead of the surgery, instead of going with my gut instinct which normally would have said "Oh THANK YOU, but I think I'll be O.K.", instead I said "Oh THANK YOU. I'm sure I will LOVE 'xxxxxxxxxxx' (fill in the blank)". That made people feel like whatever they did, it would be appreciated. And it is.
Start practicing 'receiving' the help now, even just verbally when you interact with people. And then, when people give you those numbers to help. PLEASE call them and ask for even just little things like picking you up a couple of groceries when they normally go get their own. I've found people to be SO happy to help and feel needed/appreciated!
Good luck!
