Appreciate the comments. However, I’d argue at the time I didn’t see any way of “fixing” my problems either. If we use weight as one example, you feel anxious about your appearance, being judged by others, photographs, seeing people you know. It doesn’t take “insight” to realise that there is a linkage between weight and those anxieties. The pragmatism to see light at the end of the tunnel and put those thoughts into practice is a different matter altogether, of course.
In my experience, I’ve known many people diagnosed with various types of depression and most, if not all, are well aware of their problems and what causes them. Some appeared not to have the courage (and I say that with trepidation as it takes a great deal of courage to put your hand up and say "I need a hand" too!) or even just the energy / enthusiasm / will to confront those problems and attempt to overcome them. The oversimplification, which I try to avoid, is that if you feel naff about how you look, you can get to the gym and work hard and stop eating crap, or you can claim an illness is the cause (absolving personal responsibility) and take some pills that will get you from A to B for a while.
This is interesting, my understanding is that's the medical industry differentiates between clinical depression and situational depression and it's the diagnosis and prognosis of the latter I'm focusing on more I guess (without downplaying the significance of the other). I appreciate there's varying theories as with anything, but my understanding is that those with clinical depression are either genetically predisposed to suffer or experience a sudden bout due to irregular hormonal changes in the body during puberty / adolescence / menopause. Long term substance abusers naturally suffer too, due to the sustained chemical impact on the brain (which is why I've somewhat less sympathy for my mate I mentioned earlier - he doesn't help himself)
Situational depression is, as it sounds, prompted often by a life event or sudden shock. Again, i'll use weight as that was what affected me. Let's say a perfectly healthy person has a fall and breaks both legs, can't walk for 6 months and gains 5 stone. They'd suffer many of the symptoms I did (Anxiety, Irritability, Agoraphobia, Fatigue, Low Self-Esteem) and could very easily be diagnosed if they so wish.
Really interesting, thanks. I'll look into this.
