Aw, Sylvie. If it helps at all, I remember what it's like to cry in the bathroom at work, to be so upset it makes you puke, to hear the promises and be unable to believe them anymore. From my experience, the part you are going through now is THE HARDEST part. It will get better. Probably not all at once, but slowly. And one day you will realize you aren't sad anymore. And that your life is good again. I promise.
I wish I could come help you pack.
