You're getting wonderful help here. I just want to add to everyone else's advice to stay positive. You might feel helpless now, but all of this is going to forge you into one strong, amazing woman. I know! I've met other women who have been in your shoes and made it through (one her husband did come back and two forged ahead and have great lives now... one stayed divorced for about 10 years and last year met a very wonderful and caring man).
Good things will happen for you. Just hang in there.
There is no arriving, ever. It is all a continual becoming.
