Well I finally got to the root cause of the itching, I had it right in an earlier post bedbugs -ugh. Must have picked them up from the train. I now have the wonderful task of deep cleaning my bedroom and then calling the pest control guys. I doubt I'll sleep tonight knowing that I'm not alone in here. I am exhausted at the best of times, the thought that I've got a load of unscheduled housework is just too much.
To those of you that struggle with keeping up with the chores

I hope you don't end up with similar issues. I'm trying to tell myself this isn't down to me, it is just bad luck, I'm not convincing myself.
