I don’t have chronic fatigue syndrome, but I do have chronic fatigue due to cancer treatment.
Before I started treatment, I was reading about side effects and one person described the fatigue as being too fatigued to chop a carrot. Like she was trying to chop a carrot to cook dinner and literally could not continue. Her arms and hands couldn’t chop the carrot and she needed to sit down. I thought that seemed absolutely bonkers. Who can’t chop a carrot? I get it now.
It’s like wearing a moon suit. Your arms and legs feel like they weigh a thousand pounds. Walking takes like 10x the effort it used to. Some days I can’t chop the carrot. I can’t stand to cook for more than 10, 15 minutes. Walking up stairs feels like I am dragging sacks of flour behind me. It’s not tired. Like I can’t sleep (though I do force myself to lie down so I’m not moving around). It’s like your cells run out of energy.
Imagine (assuming you aren’t a runner) that you had to get up right now and go run 2 miles. You might manage most of mile 1 okay if you pace yourself. But at a certain point, your body will give up. You won’t have enough oxygen or energy getting around to your muscles to run 2 miles. You will start grinding to a halt. Muscles will be burning. You will be breathless. It’s like that, except just trying to take the dog for a 5 minute walk.
I have a sedentary office job that involves a lot of critical thinking (well, I don’t anymore because they didn’t renew my contract). I could physically sit at my desk all day. But cognitively, I couldn’t think to do the work. Plus the pain, that’s a whole different thing. Cognitive effort and pain also run your battery down, so even if I’m sitting for an hour, if it’s painful, and I’m thinking, that will require me lying down and resting after.
I can do stuff. But there is a price to pay for everything. A busy day at work means I have to go lie in a dark room and I can’t cook dinner for my kids or drive them where they need to go. I need to conserve energy in one area in order to function in another, whereas previously, I’d just have a flat white and push through.
Doing too much means I can completely knock myself out for days after. For example, we went on holiday, just like UK self catering beach holiday. I did a lot of walking, but no naps, still in bed by 9pm. I made it 6 days. Came home and on day 7, my heart rate shot up, got a fever, ended up in hospital. There was nothing wrong with me. I just pushed it too much and made myself ill.
