Not feeling well today

I'm not in the best of spirits today.  Had to cancel a few lessons yesterday and I've had to do the same today.  Got a really bad headache - had paracetamol and tried to go back to sleep but I can't seem to get any relief - my head hurts while its touching the pillow!  

Was determined not to cancel any more lessons due to illness after the mess that was morning sickness (before Christmas).  It makes me feel really down disappointing my pupils and although they're all wishing me to get better and don't seem to be upset with me you can tell they are fed up.  I can't concentrate if I'm not 100% (or at least >75%) and in this job I'd never forgive myself if my lack of concentration allowed us to get into an accident.  

Wish I was feeling more energetic and positive but I'm too tired to think....

I'm so excited about the baby and wish it was June already!
