It may take time,and patience to get to the right road to help her. Love her,and be patient with her.
Has she had a recent bad experience that has made her angry,besides the 2 week hospital stay?
Doctors have made all kinds of mistakes with my treatments. Doctors, scientists,and the pharmaceutical industries are really only in the beginning of understanding what we with mental health issues are going through.
Give her time,and Love. BF
