Hi Suzy. Jeanine has said it all and said it beautifully. There isn't much I can add but to say that it's perfectly normal what you are feeling. I just kept telling myself that I'm doing everything I can to get rid of cancer and minimise the risk of it recurring or coming back.
I actually had a little get together with my girlfriends and female members of my family as a 'farewell boobies' party a few days before my op. We had a great time laughing and crying but mostly laughing. It was very cleansing. I also made sure I had everything I needed for hospital. Lastly I had a quite dinner with my husband and two children and we watched a really funny movie the night before I was due to go in.
If you can't sleep, it might be a good idea to get some sleeping tablets to knock yourself out for a couple of nights as you'll need to rest up before your surgery. I did :)
Keep telling yourself, this is what you need to do. Do some meditation and listen to relaxing music.
It's a very nerve racking time but you'll get through. Love yourself and your family right now.
Sending you lots of hugs
Love Janey xxx
