After my last post, I forgot about this blog until I received a couple of emails. Thanks to those of you who expressed concern, which touched me greatly.
The gas-man came in the middle of the night, checked for gas leaks and put a big sign on the boiler saying 'DO NOT USE'. Next day I phoned British Gas at 8am and three hours later a man arrived to check and service the boiler, and he gave me an audible carbon monoxide alarm.
Within a few days all the symptoms I'd had were gone.
The thought that I'd been breathing in an odourless, poisonous gas made me feel quite creepy. How fortunate that I often open all the windows in the house to let some fresh air in.
Up until this incident, I'd been feeling so dreary after Mr Prue's passing away that I wished I'd gone with him, and even had a few thoughts about how I might end my life. Being affected by a gas which has been known to kill people gave me a huge shock, and I've stopped thinking those horrible dark thoughts.
It's an ill wind, as they say.
