Honey, first off I would like to say that I am sorry for your loss.
Secondly, I would like you to just know that everyone is entitled to their opinion, and even on a suffering and loss board, some of the users can be uncompassionate towards others. You know what you did, nobody needs to rub it in your face, or tell you you were wrong.
As another poster said, many women do things and they have healthy normal babies. You will never be able to know for sure that the drugs and drinking caused your miscarriage.
Go to school, be the best mom for your daughter, and move on, it's the best advice I can give you. Don't take what some of these women have to say to heart, just take what us positive posters have to say to heart.
I hope you do seek help for substance abuse, if it's what you think you need, I go to AA, NA, and CA, so if you want any info on them, just PM me ok:)
