Aaaargh!!!

I'm facing the nightmare of having to re-install my computer's operating system. For others, it might be easy.
For me, it's like saying : oh, just take out the car's engine and put it back!
So . . . . this image is the current representation of my brain - tangled, and mangled and not feeling well.
The bit of light at the back is tantalising but just look what has to be got through to get there!!!!
I may be away for a few days.
