Getting a better handle on things

Ok, I've had my down day. Time to get going again. As my doctor said, This is a marathon, not a sprint.  Im thinking that my dark mood yesterday was partially influenced by the 4 days of prednisone I had to take after the chemo last week. They warned that it could mess with my head. I think it did. I haven't been out much these last few days. I just haven't felt like it. I did take the dogs for a walk in the groves. That certainly helped my mood. Today Im going to San Diego and meet Cris at the wig shop. I need her opinion when picking out a wig. So far I haven't lost any hair. But I want to be ready.
Last night I awoke in the night with my back just throbbing. It is not a kind of pain I have experienced before. It kind of goes up and down my spinal cord throbbing with each heart beat. I took some tylenol and it went away. But it is back this morning. I find it uncomfortable to sit. I hope it is from lack of use. I really haven't done any appreciable exercise for about 3 weeks. That cant be good.  I will get back at it and hope that fixes the problem,.
Who knows where this darn thing is going next. 
It has been only 3 weeks since Dr Day put her hands on my belly and discovered a mass, 2 weeks since I got the diagnosis of Lymphoma, and 1 week since my first chemo. Was there ever a time when I didn't have cancer? It's just hard to realize that three weeks ago, my life was forever changed.
It is a rather interesting journey. Not one that I would want. But what can you do?
