This disorder really started when I was 11. It wasn't as violent as it is now, but it was enough to give me panic attacks and make me scream in fear throughout the house.
This disorder mainly prevented me from doing sports. So we found a way to get me exempted from PE.
From ages 11 to 21 it was rather stable, I managed to learn to live with it, but since last year and especially starting a few days ago it has taken another form, it's more violent. I can no longer drive, I can no longer do much of anything really. And there are lots of other even more bothersome things that I'd rather not go into, because talking about them makes me anxious. This thing is a real nightmare, it's the worst thing I've ever felt. It's destroying me from the inside. It went from a simple OCD to something that concretely affects my physical health.
It's not just an irrational obsessive thought like the others, it's an awareness of something that I should never have become aware of, and the anxiety pushed me to overanalyze the thing, which created connections with other things, which worsened the problem over time. I know this is incomprehensible to you, but I'm doing my best.
I associate this disorder with the Devil because it's powerful enough to paralyze you in every aspect of your life, while being impossible to make others understand, while being invisible.
If there are people going through the same thing, you can reach out, so I feel less alone even though I know this disorder is extremely rare.
