My mother became widowed a few months back. Since new years'eve she thinks every few days is New years eve again. Is that a common occurrence to get stuck? Also she seems more lost in space and at moments seem to listen yet later might repeat what she heard. At times she is very moody as well. I am lost as to how to handle her being stuck. I care for my mom but lately she seems to be a different person from the one I knew and it can be very challenging.
