Phoebe, it sounds like you need to take some time out for yourself. I wonder if your activity level is a little frantic?
Here's what I would do - get a massage or reflexology treatment late in the afternoon. Go home and take an Epsom salt bath and curl up with a book and a cup of warm milk. Listen to soothing meditation music. Then read yourself to sleep with white noise (fan?) running so you won't get woken up by noises. Keep your bedroom cool for better sleep.
If you try it, let me know if it works!
