Please don't take the diary too seriously.
If I had written one as a teenager, I am sure it would have been equally heartbreaking for my mum (or my late dad) if she were to read it.
My parents were no worse than most others. With hindsight, I know that they did their best. In fact, I think I probably knew that even then, and their best actually was quite good. I was well fed, well clothed, allowed a reasonable amount of freedom, and was never burdened with any of the problems that I now know that they coped with from time to time.
Despite that, they became enemy number one when I was in my teens. In my eyes, they could literally do no right. I wasn't happy, and I turned it all back on them even though they knew nothing of what I was going through.
I'm not going to say that I now have a fantastic relationship with my mum, but we rub along and I realize now that it is just down to differences in our personalities, and any difficulties between us are at least as much my fault as they are hers.
Hopefully, your daughter will also realize at some point, if she hasn't already, that you are not really the cause of all her (perceived) inadequacies.
