Anyone else get frustrated and cross with themselves, because they feel so shattered?

At the moment I could happily sit on the sofa and not move. I have the motivation but just the lack of energy. I've had a cold for about a month (probably different colds of course) which really hasn't helped. On Friday afternoon I gave in and sat my bottom on the sofa put on a truly corny film and tried to doze. I kept waking myself up by snoring!

but thought if I let my body rest I would feel better. Come Saturday I did feel quite a lot better, then Sunday I started to go a bit down hill, and today I have an earache just to top everything off, and never has my sofa looked so appealing!!! I'm getting out in the fresh air and exercising but still my body just wants to plonk itself on the sofa.

My brain really wants to do stuff but my body doesn't. I can decide if I should keeping pushing myself or just flake out.
P.S. Considering becoming a snail - they can sleep for three years!
