Does anyone else find this: either you sit down to do something that involves some thought and find that there are so many thoughts swirling around in your head - background noise, if you like - that you can't concentrate? Or that all this mental noise is stopping you from doing anything - like you might finish something (that'll be the day!) and you find yourself just sitting there, thinking about rubbish?
Even as I type this, I keep stopping, staring into space and finding all sorts of crap wafting into my mind. Please, let it stop!
This has been my life. I wish I could push a button, switch off all the crap and just concentrate on the job in hand ... and breathing!
