I know the major depression beast all too well, was diagnosed about 18 months ago, was likely suffering from it for about, erm, 25 years before then. In fact I was diagnosed and treated for depression, with medication and psychotherapy, for a good while before any discussion of trauma and resulting PTSD diagnosis was ever made. Something to do with the fact that I chose not to disclose anything of past traumas for a long time, until my psych more or less put 2 and 2 together and presented the number 4 to me on a silver platter... no more lying Maddog.
Anyway, I digress. Loss of motivation and loss of interest in previously pleasureable activities, and indeed in the activities of everyday life, is a classic depression symptom and one of the early signs and most enduring symptoms. And yes, as others have said, when the depression is severe or long lasting, the situation becomes a catch 22. The acts of forceably motivating yourself into activity and engaging in stimulating connecting social and other activities require the very motivation and physical and psychological energy that you don't have, which then leads to self-criticism and feelings of failure, which then perpetuates the original depression... etc.
That's why sometimes we can beat the beast through sheer willpower and self-discipline, sometimes with the benefit of psychotherapy and specific cognitive and behavioural change strategies, and sometimes only through the addition of medication to chemically lift the mood state and provide us with the basic resources to make the longer term behavioural and cognitive changes.
I was a fiercely stubborn and narrowminded medication skeptic for a long, long time. Not for me, no thanks, happy pills are for sick people, and, well, ya know that's not me, right?
But reality bit, long and hard. I fell, kicking and screaming, onto the medication bandwagon and held on grimly, determined to see it out and hang in there until something had a positive effect. Tried several, under 3 different psychiatrists - lexapro, edronax, seroquel, some other sedative i can't recall, tofranil... and of course as the issue of my diagnosis became more controversial and complicated, so did the medication merry-go-round.
Sadly, this story doesn't have a happy ending yet. Currently I have found nothing that has made appreciable improvements to my mood, or to related issues of sleep disturbance, anxiety and other dissociative and PTSD symptoms. My current psychiatrist holds the view that complex trauma is considerably drug resistent, a view that is held in some circles within the mental health industry and poo-hooed by others.
Me? I don't know. I feel beaten into empty despair about it right now, at a loss to see the way forward. Schema and exposure therapy help, they feel like the only productive things I've been able to do to date, to address any of the symptoms and causes of depression, anxiety, C/PTSD and whatever the hell else is swimming around in my broken little brain.
Maybe one day I'll want to do things and be part of the world again. I've just cancelled a planned trip to the park with a friend and our dogs today, partly because my dog is a bit sick, but somehow that was just convenient... the shame is biting hard right now, I guess not as hard as the dread at the thought of going though. And it's such a glorious spring day... I hopeI find something to do with it other than sit here. I hope I can be strong enough for that today.
