Dear Eva
This is very sad news

.......
Some great advice has been put in print already and in a positive way
The only thing I will add is....don't seek answers to your questions for some time...let them come without you asking
Play a mothers role...be there..offer a shoulder to cry on...and develop a good listening ear.
We all have a story in life...in time I hope your daughter tells you hers....
When we hear e persons story we can decipher the mindset of that person...and then we can either adapt to or influence a persons life choices..
You have a huge heart Eva.....follow it.
