It does get better, but it takes time. It's been a year and a half, yet just the other night I had a dream about ex-T. It stirred up a bunch of feelings and I still can't shake them. But it's definitely not as bad as it used to be.

Try some self-soothing skills before bed and when you wake up in the middle of the night. Listen to relaxation/nature/meditation music, light candles, use lotion, take a bath/shower, etc. Maybe take a sleep aid (herbal, otc, or prescription). Drink hot chocolate or tea. Just take care of yourself. Baby yourself.
