Luv, it is damn hard. To me the legal process and just the thought of it feels like a ton of brick on me.
But, with each passing day you gain a little bit of strength. I can totally relate to your interrupted sleep and weird dreams (some bad, some good - which are just as bad because you wake up and the reality hits).
Just try to be with some friends or even your kids they're a bit older and may help support you even if just by hanging out with you.
When is he supposed to be back? how do you feel about facing him? Sorry if it's too much to think right now but something you'll need to. Other than that just take one day at a time i.e. have a 'survival plan' for today...then tomorrow when tomorrow comes and so on.
Hang in there!!
