You have generally been very stressed lately. John mentions above to use the bedroom only for sleeping and sex. If you aren't sleeping (alone in your double bed) the corollary (still alone in your double bed) is obvious (if indelicate), and it takes your mind off other things, relaxes you, and expends physical energy.

It works for most men, as far as I know, so it might well work for women.

The other thing is never leave only just enough time to get your sleep requirement. Sure as eggs you will worry about not sleeping. If you need 8 hours sleep, go to bed in time to leave yourself the spare hour when you wake up - that way if you don't sleep immediately you can think "Hm, I'm warm and comfortable, and I can doze on a little longer in the morning if I need to".   That relaxes you adn bingo.
