She has a new child

I woke from a nightmare about my Mother , she was standing over me again . She passed Sept 20 2011 .
So I went to FB and saw my daughter had opened her account again . I did something stupid I went to see how the girls , my granddaughters were growing and found a new baby there , my grand son ... 
My heart is shattered to a million small tiny pieces , yet another grandchild she will keep from me . 
It's funny how she is friends with her next to oldest brother , one of the brothers she accused of molesting her , beating her and locking her in a closet , funny how she will let my ex husband see the kids , a man she accused of a brutal rape when she was 9 yrs old and only remembered just 3 yrs ago . ( she is 33 ) . Not that any of those things happened , she has what a Dr we went to False memory Syndrome . She has Social anxiety disorders , and depression . She is a over eater , and has gained such extreme weight she is very ill . When my ex husband was having open heart surgery she kept me from contacting him to tell him I would pray for him , she even cussed me for calling the hospital...
I just don't understand how she could accuse everyone of such horrid things and only exclude me from her life .
