sorry to hear, this all sounds awful.
i only have one piece of advice:
to do 5 really nice things for yourself this week. they can be something really simple like waking up at dawn to see the sunrise, ok maybe watching the sunset would be nicer to you. just little things you've been meaning to do. even just going to get an ice cream or whatever. break ups are truly awful, but maybe it means instead of thinking about someone else, you can totally look after yourself.
also would you like a complimentary ticket to the Sb parachute dress raffle for your troubles? the draw is sometime this month.
& if you're going to re-read the book, you should start with the list of reasons why you're Mali-licious.
