Maybe with the best of intentions, you seem to have trampled on some of your daughter's boundaries by throwing out her stuff (what you deemed as rubbish, she might not), giving her things away, etc. You seem to have confused your graciousness of looking after her child with the right to do what you want with her things without so much as a by your leave. Maybe an apology for unwittingly doing this might start to build bridges so you can address other issues which are obviously concerning you.
It is possible that you are dealing with somebody who has mental health issues. Having a good relationship with your other children which is in start contrast with your relationship with your daughter is often a clue about Borderline Personality Disorder.

Even if your daughter doesn't have BPD, the strategies in the book are very useful for dealing with anyone who is difficult.
