Hi there ~
I understand your concerns. I believe that the queasy feeling and not having appetite are related to your daughter having anxiety
attacks. I also think that you should rule out allergies if she is being around the house and doing things that she has never done before. Avoiding the allergen would then be the answer. I also think that a visit with a doctor would be helpful if the spitting blood does not stop.
I hope this helped and I wish you the very best. Take care!
