Photography therapy

I can relate to your article ‘Photography saved my life' (AP 24 February). I suffer from some of the problems you covered, along with physical problems. One is atrial fibrillation, commonly known as irregular heartbeat. This left me tired, lethargic, unable to concentrate and with breathing problems, sometimes for hours at a time, especially in the summer.

I would lay down, getting more frustrated and depressed, which made my heartbeat worsen, which led to more depression and so on - a vicious circle. I didn't have any enthusiasm for anything; my get up and go had got up and gone. The one subject I would try to concentrate on was photos in camera magazines, and I'd try to work out how it was done. What aperture? How long an exposure? If I was there and moved three paceswhich has slowed my heart rate to something bordering normal. Now it beats regularly, thanks to tablets.
