Beyond tired

I am so tired. I was yawning while out at dinner. At 9.30 pm. It's now 3 hours later, I've been home for 2 hours and I'm still not in bed. Why? Because, last night, I went to sleep early - at 2 am - and couldn't sleep. So I ended up crying. As always. I'm going to bed right.now. I have an eventful day tomorrow. I'm cutting off all my hair in the morning and donating it to somewhere. And then I have a thyroid ultrasound in the afternoon. Follow up from last year to make sure there is no change.
