Hi there,
Hope you don't mind me adding my thoughts in.....sorry it's very late! You may have sorted everything out by now, hopefully
My experience was quite different but sort of similar at the same time...... I am 22 now, but when I was 18 I was desperate to have a baby, and had been wanting to have one since I was 14. I knew that that was what I wanted for my life & it was all I could think about all the time, and I started trying to get pregnant with a great male friend of mine, who is heterosexual (I am a lesbian). When my mum found out about it she was furious at first, but started to accept it after a while I suppose. I started going through a clinic to try & get pregnant not long after that, and she was very supportive of me doing that. I know she never thought it was a "good idea" so to speak, but I guess she worked out how to try & support me if that's what I really wanted. In hindsight I am so glad it never worked out because my mum died when I was 19, and I never would have been able to cope with her death if I was trying to look after a baby too. So as I said, very different circumstances to yours & your daughters, but still similar
And I absolutely understand what you mean about 18 year olds thinking they know everything & not taking advice..... I was exactly the same. I was one of the most horrible teenagers you could possibly get, because I was really depressed for years, but my mum was always there for me. I think she must have been an angel! hehe.
Anyway, I hope you & your daughter are able to sort something out, and I know I probably haven't helped you, but I wanted to try & say that I can understand how your daughter might be feeling, but I can also understand a little bit of how you must be feeling about it all, so good luck!
Jess
