I give so much of myself away every day that there is nothing left for me. Less then nothing. Every day I look into the mirror after working all my shifts and see less and less.
If they're not compensating you for giving 150% of your energy, then don't give them 150% of your energy.
Like, tell them you need to catch a breath, take a "smoke break" (even if you don't smoke, mime vape a lil ink pen in the smoking section). Rehydrate more, piss more. Say you're dizzy. Come up with something.
Sometimes the exhaustion is more habit and expectation. If you don't go home one day, do you have more energy? (Just answer to yourself.) Like one week you were exhausted, but then home became exhausting by habit.
It's so hard to do but if you do all the things you are planning on doing as soon as you get home then you can collapse into exhaustion. My wife is good at it. I'm terrible at it.
It’s hard for me to do that too. I found setting regular reminders for it on my phone helped, at least once I get over that initial hump of forming a pattern, then it just becomes a simple “oh. Today’s my day to run laundry”. Of course, if I break that habit it becomes hard again, but it does help a lot. But also I’m no psychologist, so for all I know it could be a case by case basis
For me, it helps to have some time before work where you can get stuff done. Of course you need to go to bed earlier, which is the tricky part.
So shifting part of the free time to the morning hours.
