Rubbish guilt

Today I completely failed to go to therapy because I felt too guilty to leave work. Admittedly I don't go to work as often as I should - or indeed work enough when I'm there. But feeling too guilty to go to therapy possibly a bit stupid. Esp as now I feel guilty for letting my therapist down. Think me and the therapist need to examine my strange feelings of guilt. I fear I'm turning into Woody Allen. Not good.
