I work part time and when i feel my enegry low and i take liquid B12 and it goes under the tongue. It really helps me to be able to go on.

Oh dear don’t go there there will be better days for us just hold on .....

Resting is definitely helpful, yet so hard to retrain yourself, hard if you are a single parent/single income earner or if you enjoy your work or what you like doing.
My struggle at present is I've tweaked my diet so much & yet somehow I can't sleep at times, like only 3hrs in a day & then I'll have a week where all I want to do is sleep! I take a drug usually for Parkinson's which helps with the chronic fatigue & I think it is wearing off its usefulness.
I don't want to spend my life on the couch watching tv. I'd rather not be here.

Rest when you need to, dont push yourself too hard, a good diet and lots of coffee!

I eat lots of veggies, especially kale and spinach.
