Hi all.
I've been having problems for a long time now with concentration, and could do with some advice on it.
The problem first came about when I was studying for A-Levels. I had recently started at a new school and to start things were going really well, as I was something of a natural at the mostly-science subjects I was studying. I'd quickly acquired a reputation as one of the smartest kids there. This came to an end, however, once the second chemistry module I turned in a bad result (I was planning to revise beforehand, but my mother's boyfriend has a schizophrenic episode in the days immediately before. He asked me to kill him and ended up sectioned). I turned in a bad result (mid 30% range) in that exam, and that's when the trouble started. From that point on, I couldn't catch a word the teacher said because I was "talking to myself" in my head. I quickly went from the top of the class to the bottom.
Similar things happened to me in other subjects - maths and physics, at slightly different times - I'd have one bad result and would thereafter be incapable of concentrating on what came afterwards. The problem is this has persisted for about 20 years now.
I also spend much of my time in rumination. This is mostly imagining myself explain things to people who are important to me.
So. I mentioned this to the doctor, and was diagnosed with OCD. I then went to see a CBT therapist, but they weren't so sure (the rumination is all-mental. I don't really have any overt compulsions, and the therapist didn't seem to think much of the idea of "pure-o").. She did, however, say that she thought my problem with concentration was a post-traumatic issue, which looking at the literature also looks credible.
A year or so ago, I had something of a one-off good day- there's a maths book (about formal proofs on software) I've been having a hell of a hard time getting through. I noticed that when I picked it up and didn't understand or remember something, I had an anxiety reaction - like I was failing in a duty to know it, and people would be upset with me for not. Well, I stuck with the anxiety for a few minutes, and then I somehow had clarity for the rest of the evening. Managed to read properly for once without distraction, and made more progress with the book that night than the entire year before. The clear-headedness I felt that night is what I aspire to get back to.
Unfortunately, I haven't managed to recreate it. I try to stay with the anxiety without reassuring ruminations, I haven't quite managed it for more than a few seconds, which doesn't seem long enough to produce the beneficial effects of the other time.
I'm convinced that this is an anxiety disorder, though I'm not clear on whether it's "pure-o" ocd or PTSD (if that matters). I'm also convinced that exposing myself to the anxiety directly is the right way to go about a recovery, though I'm not sure on exactly how to go about this to produce lasting beneficial results like I did that night, and I'd welcome any advice.
Thanks
