Hi, Linda,
sorry to hear you're not feeling so well.I don't have any advice or useful info just wanted to say that
my son is also having a birthday party this weekend.
But I have been so low on energy all week too, and he is quite under the weather too.Hopefully we'll be better by Sunday though, for the party.
We're having a pirate party in the house ,normally I would be more excited just don't have any spare energy.

Like you said one step at a time,I've been doing what I can each day to prepare & my son did alot too,we made all the decorations out of cardboard boxesetc.I am turning ultra eco-friendly and will never be responsible for a balloon again, we made treasure chests ,crocodiles,
I love parties! Don't let people put you off by saying that kids parties are daunting, I think children are content to be congregated together doing their own thing,sometimes the adults put so much pressure on themselves to have everything "perfect".
Just prioritise and keep it as simple as possible is there anyone around who could help out a bit in the preparation?
Hope you feel better and can enjoy the party.
