As far as the spots, I cannot speak to, I know it's hard not to worry. All I can offer is what I tell myself, and everyone else in earshot. Worrying just takes up time out of today. Right now, this minute, today, you have nothing to worry about. Tomorrow, if your told that the spots are something bad, then you HAVE something to worry about, but even then, what does worrying do? I take it one step at a time and tell myself, I am OK, everything is fine, then when I'm told that I have a problem I tell myself, it's still ok, the docs will figure out how to battle this, and I am all in, let's go, get after it and beat it back again.
A positive mental attitude can be the most powerful medicine you will ever get, and your best weapon against the disease that's trying to get us. I choose to not let it win, and let it, and everyone else around that I WILL WIN, IT WILL NOT.
All that said, it's hard to keep your mind out of the negative places, but try. Keep your mind on what you want, and off of what you dont want.
Best of luck to you, plan what your going to do to celebrate in 2 months when your scan shows nothing!
