Recovering but tired

I'm so tired. The antibiotics had an effect some hours after the first dose. My nose stopped running, fever went away. But I am still SO TIRED. The crushing fatigue. I feel somewhat better when I first wake up, but after a few hours I am right back to being exhausted again. Most of the time I am too tired even to read. It's not just my body, my BRAIN is tired. Sometimes I get a second wind in the late afternoon/early evening (after resting for hours) and when that happens I try to clean the rabbit litter box or cook a meal. The other night I managed to do a small amount of work.

My life used to be like this every day. My 20s were basically spent in this haze of exhaustion. It's really amazing that I ever went to college. And I have enormous gratitude that my health has improved. But every time I get sick, it takes me weeks and weeks to recover my strength, no matter how hard I try to rest. It's very frustrating, because so many things go undone.

I am going to try really hard to rest this weekend. My Tai Chi instructor was kind enough to credit my enrollment fees for this round of classes on to the next one, bless him.
