I'm tired and I want to go home.

Is it true?:

This one pops out of my mouth when I'm fatigued or feeling overwhelmed. Sometimes I space out and say it when I was fine the moment before. I don't think this is tied to now. I think it comes from working too long time at jobs I hated, where the management style was abusive. True at one time and still true at times if I'm not taking care of myself by getting enough rest or if I stay in a bad situation when I need to go. Sometimes in life it's necessary to keep plugging away at something that is not pleasant to deal with.

Can I absolutely know it's true?

Sometimes I think the feeling bleeds over and poisons moments that aren't that bad. Just thinking about it now is exhausting me.

Who would I be without this thought? think I would have more energy and the fatigue would not feel so crushing.

I'm tired and I need a break, maybe I should go outside and walk a bit.
