towing the line at home and fatigue after work

I have really noticed for myself that I become very fatigued after a while working

either driving for my parents or working at the market (and this happens after only a few hours).

I think fatigue has a major roll in my own mental health challenges.

I am naturally probably very spontaneous, but I try to focus and I know it also takes all of the energy 

I can muster to keep things clear and framed for myself in a kind of perspective

that helps me interact peaceably and responsibly with others and myself..

When I start to fatigue after a few hours - then the mind starts to go all mushy - all those side

effect of my challenges that I've discussed here

and with that I lose a lot of my effectiveness. So, as a result I know I need rest..

I also know that part of my independent life is about me 'towing the line' in my life.

Doing the responsible things to take care myself - and also - that can mean - just the very

basics of keeping myself occupied, entertained, as well as the practicals.  

I thought I would write about it here - just to talk about it...

Maybe someone will see something of their own experience too?
