I know you are frustrated because you didn't feel your therapist picked up on your mood. She probably realized something was wrong but was not sure what. Depression perhaps. Recently I was bummed when I saw my therapist but it was not depression for me but fear and huge stress after learning I owe the IRS a gazillion dollars (feels like it anyway) and I am terribly worried about my son who is failing in school and I don't know how to help him be self sufficient.
I do hope you are feeling better soon.
