Advice on how to cope with depression and anxiety isn't in short supply, but it's unrealistic to think that everything works equally well for all people. This isn't just true for self-help of course, but for a huge range of human experiences.
Take sport, for instance. A coaching tip that connects with one person might have no impact on another. As our friend told us, after years of struggling, his skiing was immediately improved when his instructor explained that turning required the same shift of weight you use to dodge around an opponent in rugby. It worked for him but not for anyone else in the group.
The moral is, try lots of different things until one connects directly with you. You don't know what it's going to be until you give it a go. One Moodscoper told us that for her, the best coping mechanism is a particular form of exercise, not exercise in general. Her guaranteed antidote her is circuit training - a gym session where you go through a prescribed set of exercises, moving from one routine to another without break, followed by a period minutes of stretching and relaxation.
She's tried many other forms of working out but none came close as a mood-booster. She's not exactly sure why circuit training is her thing. Perhaps it's because you have to follow a set routine, with no room for decisions. In a way, it doesn't matter why it works so well. She's just glad that she discovered an infallible method of lifting her mood.
