At times, lost and adrift

Over the past few days, feelings of being lost and adrift have really intensified. What am I doing here? How did I end up doing IRB work for 9 years? Why am doing clerical temp work right now? In truth I've not lived up to my potential and my talents and I'm paying the price for drifting through life. Not sure if it's fixable. I've put up a lot of walls in my life and I fear that they're so high I can't get over them. Well, don't we all build our own prisons? Just some remain with their fellow mates while others tend to dwell in solitary confinement more often. Pass me the stale bread and filmy water.
