The idea we can do things to sabotage ourselves is one of those concepts that has much common sense appeal. Yet what are we actually saying when we describe ourselves - or other people - as being self destructive?
Most often it's a throwaway line: "I don't know why I did it. I guess I'm just self-destructive". Without doubt, many things we do - that may not make much sense to us - can seem that way.
Drinking or taking drugs to excess, deliberately hurting ourselves, arguing with and hurting those we love, avoiding important meetings or even job interviews, can all make it look like we're our own worst enemy.
The problem when we just shrug our shoulders and accept ourselves as "self-sabotaging" is it doesn't help to us understand ourselves. In fact, it can leave us feeling that it's something we can't change.
But if you look closely enough even the most self-attacking behaviours can be understood. And if we can understand it we can also change.
Take self harm, for example. It seems to be a clear, deliberate effort to cause ourselves pain. But quite the opposite is true: self harm is an attempt to manage intense emotional pain - a form of intense distraction to shock attention away from painful thoughts and emotions. The physical pain is the price of ridding one's self of the emotions.
The key, when we try to make sense of these things, is not whether they are a deliberate effort to hurt ourselves. It's asking, what is the short term payoff? Seen from this point of view, all these behaviours make perfect sense. They are either an attempt to cope with painful emotions or overwhelming tension, or a way to avoid them.
We bail out of the job interview because the performance anxiety is overwhelming and we fear failure: avoidance offers short term relief. We drink or use drugs to escape distress and tension, even though the long term costs - hangovers, health problems, addiction - all outweigh the short term relief.
It is human nature to favour short term relief. And no more so than for people who have experienced chronic childhood trauma, or are, for whatever reason, in the grip of overwhelming distress.
We all make seemingly "bad" decisions when the future ceases to exist.
There is an old maxim in therapy that we need to cherish and respect our defences - those things we do to get us through tough times - because they helped us survive. To see them as self destructive is to dismiss as wrong that which enabled our psychological, or even our physical, survival.
Of course, everything human beings do makes sense - if you know enough about the situation. So if you find yourself judging someone as self-destructive, it probably means you've failed to truly understand the pain they're in, or have been in in their past.
