Ups and downs

When I was first diagnosed with breast cancer I was told by women that had been thru it that I would "feel" every ache and pain differently now. Every time I had a cough that lingered I would think, "It's back - it has come back in my lungs" or if my bones ached then it would be, "Now I have bone cancer, I just know it!" I didn't believe them, really, and probably because it was all so new to me and I had no idea what I was getting into. Well, I can tell you that it is true. I've said here that I will not worry about the cancer coming back because it either will or it won't and worrying about it won't change that. Oh that sounds so good, doesn't it? So easy?
The mind is a scary thing. It can take a very small thing and if one dwells on it long enough then that small thing can be blown up into something that is too big to fathom. My aches and pains have done this to me. And it doesn't bother me all the time. Just sometimes. Somedays my ribs hurt under my breasts and I just know that the cancer has spread. Or I keep coughing and coughing and swear that next time I go to see the Onc. that I will have a chest x-ray and they will find "it". Why do we do this to ourselves? What does it help?
I had hoped that I would be able to know my body well enough to feel if there were any changes. But hell, I didn't even know I was sick in the first place. So how do you know? What do you do?
When someone comes up with an answer let me know. And don't worry. This is a down time but I will be back UP!
Peace to all of you. Namaste'.
