I did find during my cancer experience that I had to take care of my own emotional needs pretty much, there isn't a lot of time during regular informational appointments to spend on "how are you coping with all of this" - and my care was from top providers here in the States. I read a lot of medical literature and I know that Canada has some good cancer centers, just as we do here (and maybe some not so great ones, just like we have here). You may just have to seek out your resources rather than continue with the fatalistic attitude you seem to be having right now.
Look, a crisis can only last so long. There's little choice but to get through it. And as you do, you generally come to acceptance after two or three weeks. So the way you're feeling right now won't be the way you feel two or three weeks from now, in other words. But you need to recognize it as a grieving process, with all the stages that one goes through when they grieve - shock, denial, anger, bargaining, and eventual acceptance. Until last week life was going along all fine and good for you until you had a medical scare. All of a sudden, your own mortality is in front of your eyes, perhaps for the first time. If that's the case, consider yourself lucky you've had it so good up until now! Many people around us suffer with these issues every day and we don't always pay attention to them if they don't affect us personally. So now you're one of us who've joined the ranks of having a medical scare. It's as good a time as any to figure out some coping mechanisms that will help you now and also model for your daughter. Consider it a gift to her to see her mother fight whatever she's facing with strength and dignity.
Even though we don't know if you even have a diagnosis yet, look around at some of the fighters we've seen in the breast cancer community and all the good work they've done to get us to where we are now. Of course, it always helps us keep it in perspective, too, that we're dealing with one of the more treatable cancers thanks to all the hard work these warriors have put into the cause generally because they or their loved ones have been affected by it one way or another. June is usually the time when Relay for Life runs. Not sure if you have those in Canada but if you have a chance to participate in one, it can be a very moving and motivating experience that makes you realize you are not alone in this. Many, many people have had cancer but they don't really talk about it much, generally, unless it comes up. Once you start talking about it, though, you'll realize how many people have fought the fight before you. One of the most moving experiences I had at the Relay for Life was walking the walk arm in arm with two women close to me - one who was also in treatment at the same time I was, but also one strong warrior I knew locally but I hadn't realized she'd even had cancer before that night. I can't tell you how empowering that was for me! As it was seeing the counselor who'd helped me so much emotionally at the end of the walk. (Ok now I'm sitting her with tears in my eyes remembering this - thank you for that because it's good to remember even though it's slightly painful.)
Hang in there. Take some deep breaths and start to think positively about how you are going to get through this. Actually picture yourself remaining strong, walking hand in hand with your husband and daughter in the sun light, having good times at Disney again, etc. These are called affirmations. You can find sayings to say, too, there are lots available all over the net. Sometimes going through something like this helps make you appreciate things in a different way afterward; to not sweat the small stuff, etc. I know before I had BC myself it was a subject I didn't even want to think about. I had no reason to, really, it wasn't something that affected me or any of my friends and family. Until it did. (Of course, once it did I realized it actually had affected more people that I knew once I opened my eyes to it.) I was in a gift shop the other day at a cancer center and I picked up some head gear that they sell for people with hair loss. I was remembering we were discussing it recently on the Breast Cancer thread and I wanted to see what they sell these days. Anyway, handling those headpieces, and seeing some women wearing them around the hospital, brought back some difficult memories for me. And I said a silent prayer of thanks that I was still here for my family and have gotten to see my kids grow up and helped them become good people (as I promised I would during the bargaining process), etc. It is a part of my life that I accept happened, and I am grateful that I got through the experience and can hopefully help others get through it, too. It does give me a perspective I really don't think I would have otherwise had, despite working with sick people myself, so in some ways I am grateful for the experience and I don't wish it away.
