timing gone wrong

my sleep timing is all haywired now. I can't sleep even though its 1:30AM. and I've found something new to be depressed over. damn it. it seems I'm always bugged by such things and unlucky too. tomorrow morning I shall return to camp to serve the last 24 hours of my standby duty. the standby duty honestly is fantastic. it's basically eat and sleep. even the food and drinks served are good. the only downside is that the off times are erratic. I'll miss the duty days. they were like holidays. and about that issue that I'm depressed over - I've confirmed it just today that there is something wrong. It's disturbing me. What a sad world.
