Where did I go wrong with my daughter? She's .?

I'm going to have another baby before I hit the menopause and I want it to be raised better than the daughter I have already. I went wrong with her somewhere along the line and she turned out a . I tried my hardest but I must have done something wrong, how can I stop this happening again? I don't want another dissapointment for a child. I mean, I tried my hardest on her. I'm aiming this question more at other mothers, maybye with daughters/sons who think they're gay, but I would appreciate help from anyone really, thanks.
