Sometimes i can go from ok to mentally and physically drained in the way that an F1 car goes from 0 to 60.
The stupid thing is that more often than not there seems to be no discernible trigger just this overwhelming sense of anxiety and guilt that makes me feel mentally and physically exhausted.

I sometimes wonder whether such a sudden and immense feeling of anxiety and guilt may have it's manifestations in a long ago childhood experience .
Or perhaps i am being silly for thinking so. The incidence occurred when i was 9 and at boarding school. I was waiting with the other pupils for the headmaster to come in and take a class. Some boys like myself were waiting quietly for his arrival while others were being rumbustious as young boys can sometimes be.
Cue the appearance of the headmaster and as the door opened a hurried curtailing of noisy activities.
He singles me out to be approached and says in a stentorian manner 'What are you doing' to which i replied 'I am doing nothing' meaning i had been sitting quietly waiting for his arrival to which he shouts ar me in a disapproving voice 'you should be doing something' and tells me to wait outside the study to be given the cane.

I often wonder the sudden bouts of free floating anxiety and irrational guilt are to some degree a product of that long ago unnerving experience.
