I've always thought it's a fine line between anxiety and depression. Sometimes I'm hard put to distinguish between the two and if you asked me to describe the difference I might have to get back to you on that.
I've always considered my tendency was towards anxiety and of the two I would find that the least challenging.
Claire Weekes didn't have a lot to say about depression: she preferred to call it 'depletion' and considered it to be the result of nervous exhaustion. As I'm a Claire Weekes fan I have to admit I know much more about anxiety disorder than depression because she was concerned more about anxiety.
So let's consider some possible reasons for depression.
1. Chemical imbalance. This occurs when genetic imperfections supply us with too much of one hormone or too little of another. A whole multi-trillion dollar/pound industry has grown up in an attempt to restore the balance with medications. Let's remember this is a relatively recent science, when Claire Weekes wrote her first book back in the 1960s there were really only two mind-changing meds: barbituates that made you sleepy and the wonder drug Valium/diazepam which gives instant relief from anxiety and remains a wonder drug in my opinion despite recent attempts to demonise it.
So pharmaceuticology in general is still very much an infant science. Weekes' method for full recovery from anxiety disorder only advocates taking 'sedatives' and bed rest for short periods of time in extreme cases so stands apart from the pill-popping approach to recovery.
In fact, I don't think Weekes had much sympathy for the 'chemicals out of balance' theory which she considered a symptom rather than a cause of anxiety and depression. I think she thought that following recovery through her method the chemicals in our brain would return to normal balance. I think she thought apparent inherited tendencies were caused by nurture not nature.
2. Anxiety is so depressing. This school of thought is based on the belief that having to face exaggerated anxiety every day can lead to a feeling of depression. So depression is a secondary condition: solve the anxiety (and the overwhelming pressures that can cause it) and the depression will yield too. Because there's nothing left to be depressed about.
3. Nervous exhaustion. Constant stress and worry can wear anybody down. Some sooner, some later. It's usually accompanied by too little sleep and inadequate meals due to loss of appetite. Total exhaustion can have a detrimental effect on our mental hormones/chemicals that then precipitate feelings of depression. Removal from those overwhelming pressures and plenty of bed rest, good food and spending your time on interesting pursuits are the antedote: where did convalescent homes go to just when you need them?
That's the story. Three possible causes for a mental health tsunami that appears to be reaching pandemic proportions amongst the young as much as the old.
