No, I don't believe it is, but sometimes it feels that way.
I've lived with a nearly constant low level depression since my teens, but when it flares up, it's always in response to something bad happening in my life. Or the culmination of a lot of little problems or petty annoyances that grouped together, form one big problem.
This makes me question the validity of depression. I mean, a lot of people have problems. Some have more than me. And it's a fact that life will regularly throw roadblocks and obstacles in your path. Other people just remove those roadblocks, or navigate around them. I can sometimes do that too, but when they get to be too frequent, I am more liable to just give up and be miserable about it. This bothers me.
They say depression is largely due to chemical imbalances in the brain. Fine. Then why don't my major depressive episodes just happen? Why are they always a result of a sudden problem, incident or trigger? It makes me feel like a weak person. Someone who would rather crumple into a heap of despair than take action.
Don't get me wrong: this is not a 'depression isn't real' post. But why can't I just pick myself up and move on when something bad happens? Everybody else seems to be able to do this. I just sit there and whine about it. This does very little for my sense of self-worth.
I get to feeling ashamed of my depression because it seems to me a passive, defeatist reaction to life's little turds, rather than a proactive one.
So is depression just an inability to deal with life's curveballs?
