Remember that frustration you have felt when you know you should have gotten something that you missed out on? How that frustrating builds to a strange, helpless rage as your goal or prize continues to else you?
The you start to get angry at yourself and doubt yourself, wondering if you are doing something wrong or if there is something wrong with you. You know you are unpleasant to be around like this so you can't seek help or comfort from friends or family.
It might have been understanding something in school, being unable to break through a barrier in a physical activity and see the results you want like weight loss. It might even be as simple as a video game, trying to play the same part over and over again and following all the instructions and guides and still failing.
For me it's sleep. I lie here awake hour after hour, night after night, year after year for over a decade now. And then when I do get to sleep if I wake at any point I suddenly find myself locked out, unable to return to that wonderful world of dreams. Most nights I'm resigned to my fate, the constant exhaustion is just a backdrop to my days. Other nights while I lie here pointedly awake or on the cusp of sleep, not quite actually there, I start to think about myself. Wondering what I'm doing wrong so that I can't perform this simple task that all humans and indeed every animal on the planet has evolved to do.
Anyone else had the same or similar experiences? It might be getting to me just a little.
