1. I feel well-rested, even energetic. Life is good.

2. I'm a bit off today. Not too bad, just not a lot of pep.

3. I'm tired. I think I need to get more sleep.

4. I'm really tired. I'm getting desperate for some rest.

5. I'm as exhausted as I've ever been when I was well. I feel like I've been working really hard, with very little sleep for 3-4 days.

6. It's a struggle to function at all. I feel like I'm walking through a lead fog. Getting anything done is a sheer act of will.

7. I'm no longer functional. Just getting dressed has exhausted me. I'm either lying in bed or sitting on the couch.

8. Forget getting dressed. Just getting from the bed to the bathroom to the couch is all I can manage.

9. Need help to get from the bed to the bathroom. Forget the couch. I'm too weak to sit up.

10. Can't get out of bed without help. I'm terrified that I won't have the strength to take my next breath.
