I made the appointment, thinking, "I don't really need this, my memory's been getting much better lately."
In fact, I'd been telling myself I had been feeling really good, generally, and that everything was getting better.
I walked the dog every day for a week. I convinced myself that the exercise was good for me, and I was actually feeling better in all ways.
Then I got the phone call from the doctor's office asking why I'd missed my appointment. I'd forgotten to go.
Suddenly, I realised just how exhausted I actually was. I looked at my pill sorter, and noticed the number of times during the week I'd forgotten to take my meds.
I went to bed. I stayed there for most of the week, and and probably not yet quite back to where I was before I decided to exercise every day.
My son's been walking the dog. This has made the dog much happier because he walks further and faster than I do.
The lesson from all this is that yes, I do have limits, and constantly pushing past them isn't going to make them go away, it's just going to make the crash worse when it comes. It seems I had learned that lesson a few times before, but I've kept forgetting it.
The other lesson is that, yes, I do need that appointment for my memory.
