Triber Glenn: "I am all too aware of the effect the changing of the season has on some sufferers. Without the sun, it sometimes becomes an impossible task to get out of bed on a cold grey morning. The mind is saying 'What's the point?' Well, the point is you have to fight and draw on your reserves of willpower. If you don't, then once again the black dogs are wagging their tails in joy at another victim. You have to make that almighty effort to fight. The sun will come again."
