So much to do, so little time for nothing

Eight to twelve hours at work five days a week. Either game or events on Saturdays, then Sundays are either visiting with family/doing laundry/rapier practice or more event stuff. Monday, Wednesday, and Thursday evenings after work are for exercising, and Friday is more rapier practice. I occasionally get scheduled for a half day here and there, but inevitably someone calls out and I end up working the whole day.
That bugs the ever-living snot out of me. I feel like people see that I’m scheduled off-unless-needed and decide to suddenly be “sick” when they really just want a free day.
Why don’t I get free days? I don’t blame my bosses; they have to staff the clinic as is necessary. I kind of blame my coworkers sometimes though. Okay,¬†most of the time. I mean, do they realize the kind of life I lead? If it wasn’t for my early-morning insomnia I’d never get anything done outside of work. No writing. No sewing. No artwork. Nothing. Just because I’m not out partying every night or don’t have kids to take care of doesn’t mean I don’t have things to do.
I’m tempted to request off more often just to get a break here and there, despite the need for PTO when I actually¬†need the off days. I just can’t seem to catch a break.
Maybe this afternoon I’ll get the half day I was hoping for.
Maybe. But I doubt it.
