I'm reading Tim Cantopher's brilliant book on depression. He opens by stating the obvious. If you never give a shit about anything or anyone you're unlikely to suffer from depression.
If on the other hand you care deeply about what you do and how you are seen by others, then the black dog of depression might come scratching at your door. So as the title suggest, depressive illness is a curse of the strong, not an affliction of the weak.
Now I know it's good to flatter your readers by telling them they're strong, but this Cantopher is a psychiatrist, not some charlatan peddling 'mindfulness' or 'wellbeing' programmes. There are simply too many opportunities to spend money with those striving to live out their dream at your expense.
Cantopher also uncannily puts his finger on the root of my problem when he quotes Simon & Garfunkel. Yes, I do 'hear what I want to hear and disregard the rest,' I've long scorned praise and ignored evidence of success.
There are no magic cures for depression. It's biochemical and bloody horrible when it gets you. I attribute psychotherapy and strong pills for the reason I'm still alive.
So where's the upside to living with depression? Well we all learn at school, for every action there's is an equal an opposite reaction. In other words the crushing lows are interspersed with episodes of amazing clarity and creativity. Make allowance for my bad days and benefit from my good days!
