First of all this is about me, not a judgement on anyone else (bar myself perhaps)
I have a chronic illness and have had it for years. At my worst, I basically needed a carer. I didn't have enough energy to cook for myself, clean the house, put the washing to dry etc... I did two things. Go to work for about 10~15 hours week ( over 3 days) and do the emotional labour involved in having two dcs. That's it. If Dh hadn't been aorund, I wouldn't have been able to look after myself, let alone my dcs.
I have slowly been getting better (Hourray!). I am looking back at how i was and I am wondering why on earth I didn't just stop and take the time to recover rather than trying to push through (and probably made myself more ill in the process).
It made me wonder, what could be a 'cut out' to actually throw the towel and say 'Now I stop'? At which point would you stop working?
