What a wonderful parent you are! I know that my mum finds in so difficult to cope with me at times. I attempted suicide at 18 as well however my mum doesn't know about it as I was at uni at the time and I don't think I could ever tell her but to hear that you are so supportive of your daughter regardless is something to be so proud of. I take quite a lot of my feelings out on my family and it's probably because they won't give it back. Although she doesn't show her gratitude i'm sure she is thankful of your support and I hope she comes through this and starts to appreciate the way you are being but you are right... only she can help herself and i'm sure in time she will. Don't give up but remember to take time out for yourself.
