Weary/ Chronic Fatigue

I realised how tough yesterday was for me when I burst into tears at about 9pm and couldn't stop crying for about an hour. I was exhausted from the time I got up yesterday, but dragged myself to work (in a taxi that cost me £30!). I managed to get through the day, make myself tea etc. when I got home - and only when I checked Facebook did I break down over an insensitive comment someone made.
The weariness has carried on into today. I had a day off thankfully, so I was able to have a lie in. But I've not left the house (apart from to get some bread rolls from across the road - but that felt tiring!). I've spent the day watching Netflix and napping. Hopefully I'll be ok to work again tomorrow...
