Want to walk more but too easily run down some days; dancer cancer/back surgery rehab

I'm frustrated.
I must have slept 14-16 hours yesterday. My body just shut down. It was bad. I couldn't even focus. I tried to watch Blue Bloods (love me some Tom Selleck, dating back to Magnum...) and had trouble keeping up with the story line.
My physio, Paul Peres, says that it's completely normal. I'm caught between rehab and real life. I'm just shy of six months out of the hospital. I'm working 30 hours a week. I'm trying to keep up with my share of the chores around here, doing dinners and laundry, so that Carol-Ann can get a break. I'm walking more and more freestyle. I've even taken to leaving Evander (The Cane) at home for jaunts to Vancouver Giants' practice and other work trips.
Paula says there are going to be days when I simply break down. Doesn't make it any easier. It still sucks.
I will be looking to change things up. Paula's down to visiting once a week and she says that she'll be all but done with me come early December. To keep things going, I'm planning on picking up a trainer -- I'm meeting Monday with Sheila Townsend and Jesse Tupper. The married couple are former UBC athletes and I covered them both. They just opened up their own gym and they know my story, so I like the connection.
Not to be a downer, but there's a chance that the cancer could come back. We've been told as high as 70 per cent chance. I need to be ready to fight if it happens again.
Things aren't all bad. I had dinner last Sunday with my first GF Strong roomie, Mike Sidhu. Mike was a good role model for me. Some people at GF do their routine classes, but little else. They lie in their beds all day. Mike was always on the go. Always doing something.
He's doing at his sister's house in Langley. He's doing pretty well, but he's still got his challenge.
That's something I get.
