I have is not been around much, so I don't know if you have already shared in what way your daughter is having a hard time, or even if you feel like talking about it.
Your daughter is the same age as my son, and the one thing I have noticed with him is that although he is normally very even-keeled, when he escalates these days, it extreme and not typical for him at all. Last year in school I got a call from him saying that he was freaking out in school, that he couldn't take it anymore, and that he was going to hurt himself if he had to stay in school. Needless to say, that made me freak out. In working through it with him, he did not understand that saying you are going to "hurt yourself" is a euphemism for suicide. He was literally talking about breaking his finger or arm. But that still shows the extreme stress he was under.
The interesting thing is he is no longer in a mainstream school district. He is in a special STEM high school that is designed for kids who are not performing to their potential in regular school. He goes for 6 years then gets both his HS diploma and an AS in computer science. To give you a picture, my husband went to one of their science-fair type days and came home and said to me "you didn't tell me this is a school for kids with Aspergers." It's not. And although the kids are mostly quirky, I don't think most of them are on the spectrum. But my point is, even in a "better" environment than a mainstream HS, he is still struggling. I think a lot of it is the age.
14 was a VERY hard age for me. Looking back, if there was one thing my parents could have done that they didn't, it would have been to acknowledge that I was not like other kids, that I would never be like other kids and that it was 100% OK that I was not like everyone else. I think their tacit belief that I was "normal" made things so much harder for me, because I knew I wasn't, but there was no support available for me to be anything but normal, and I had no choice but to fail. ANd I was painfully aware of it at all times.
Your daughter is already strides ahead. She has you. And even though you may make many mistakes, she has you. And she knows you understand. And, at least looking back at the 14 year old me, that may have been the only thing that could have helped make those difficult years more bearable.
