I can honestly say this pre surgery period is the toughest as everything is still new and there are so many unknowns... I know it is hard to breathe at times and so many weird and at times scary thoughts run through one's head BUT it gets better.
You need to prep for the surgery and I would honestly advise to rest up as much as possible, have a few outings with your friends and family and use this time to recharge the batteries so you have energy for the recovery.
There are a lot of posts here about what to take to the hospital and what various people found helpfull to do ti prepare so will not go on about it as I know you can easily find that information in the search histories...
I guess just wanted to say that once the surgery is over and done with and the cancer has been removed there is a lot more certainty. You can breather out... You will soon also have the final biopsy results which will determine the appropriate treatment and then you have an action plan. It really takes away a lot of anxiety so just hang in there.
Remember to take things one step at the time and to take care of yourself and to let others help you. Do whatever feels right for you at the time. There are many mixed emotions (we have all been there and I remember going from a superwoman mode where I could take on a world to a raging maniac to an absolute meltdown due to sooking and almost depression in a space of 5 to 10 minutes...).
Just remember this is one of the hardest if not THE hardest thing you will ever do through so do what feels right for you. Take care of yourself and remember this forum is one safe place where we get it and are here for you.
