Last winter I had a touch of depression. I didn't realise at the time though because it came out in the form of social anxiety attacks. The thought of going out and socialising, or even going busy places with lots of strangers (e.g. London) was all a bit much for me. Life circumstances have changed and that has all passed now but not without a fair bit of fight.
Adventure needs to be thrust upon us from time to time. Otherwise it is all too easy to become anxious and depressed at the monotony of life. We can become fearful of anything outside of that. Going from point a to b in a straight line is all I do. To do anything else felt illogical and a waste of my precious energy. That is until one day.
