hello Gracie and welcome, but of course sorry that you find yourself on this thread.
I hope we can all help you along the way, - we do hand holding, and take turns to plonk our (in my case ample) bums on the paranoia box.
I'm nearly four years past DX - so a bit of an old timer, but - I hope it's reassuring to hear from someone who's been where you are now, and is a bit further along the road 
And of course there are loads of great women on here who are at a similar stage of their journey to you, and can truly understand what you are going through.
I too went from being a person who rarely bothered the doctor, to raving hypochondriac 
- but I don't think the docs. mind.
Breast care nurses are often very good people if you need to talk thing over and say stuff you can't always say to family and friends.
I am so sorry you have also had to deal with the loss of your Dad. I lost my own darling dad just before Christmas, and it is such a hard thing to cope with, then for you to have your DX on top of that, must be so difficult. Loads of coming your way.
Your colleague sounds mad as a bag of badgers 
Anyway stick with us, waiting for results is shitty, but someone will always be around for a chat if you need a shoulder
waving to everyone else, at MAS and LJ laughing at my compost comment - rather revealing about my priorities in life
Hope you're feeling a bit calmer this evening Gig. - meant to ask earlier, have you got decent pain relief for your infection? - because if it's hurting a lot, that will make you feel down.
