Cry it out
think of one small positive...then another and keep it going ...you will start to feel better and slowly drift into a good slumber!
Talk to yourself for sometime.
Brew yourself a warm cup of tea, breathe deep, sip slowly and sip till the last drop. Then take a walk in a local park or anywhere in your neighborhood or even inside your home and let your heart's heaviness ease with every step.
Nice food, hot drink and funny youtube videos.
Release the burden in your hearts and cry and you will be able to sleep. Think of happy thoughts. It always work.
scotch works for me
sorry, try warm milk and a bubble bath
and i'm here if you ever want to talk about it
