Okay, so I've called an ambulance

I'm just geting weaker and can't fight it any more.

Many thanks to to the commentatators who have pretty much confirmed what I think is wrong with - alhtough only time will tell for sure.

I don't have a smartphone or tablet, but have packed my laptop and will hopefully be able to keep in touch with that.

Please wish me luck, my blood is very thin and I do't heal well - I'm absolutelty terrified.
