It has become quite well established, that shifts in ones sleep-wake cycle, are significantly bad for ones health (both physically and mentally)
...which is far from the main reason that I am depressed about having no consisteny to my wake-up schedule.Irregular sleep-wake rhythm
is quite a serious disability...
Unlike minor disabilities, like being paraplegic, missing all four limbs, or something like that.
You can work, go to some club or something, on a, very much, regular basis, have no trouble setting (and keeping) dates on which to meet friends...?
In what way are you disabled, then?
Sounds pretty able, to me.
