So yeah this post probably won't help me, but maybe it will be somewhat useful for someone else. I wasn't sure whereabouts on the forum I should post it.
(possible triggers)
I suffer from exam phobia and have done for about twenty-five years. Throw in neurodivergence, trauma etc. to make things more complicated.
There seems to be a hell of a lot of unhelpful misinformation about exam phobia / anxiety. The "solution" for it is usually just to "prepare more", for example. As if that will cure it.
Have you ever heard of accomplished stage actors who may have been acting for decades, have won many awards, practically everyone considers them to be great actors.. then they develop severe stage fright and aren't able to go on stage. Hmm, maybe they should just "prepare more" lol.
Obviously being prepared for an exam CAN help in some situations, but it's definitely not a silver bullet or anything. I go to driving instructors and they're surprised by my driving ability and knowledge of the rules of the road. They're surprised I don't already have a full driving licence (I don't live in the USA in case you're wondering). So I'm pretty prepared.. guess what, my exam phobia doesn't even let me show up for the test any more, I get severe mood swings and cancel the test days or weeks beforehand. Please don't try to encourage me to attempt that thing yet again. I even get intense flashbacks to when my issue with exams developed as a teenager, gee thanks brain! Lol
I've tried hypnosis. Feels good at the time, but doesn't work and even seems to ultimately make things worse.
One thing I might try is yoga belly-breathing or whatever the correct term is. I have tried diaphragmatic breathing but I won't be doing that again as it may have caused me some chronic pain which thankfully went away eventually.
I have to be wary of some techniques like visualisation as they might make me feel confident and even a little "high" in the short-term, but that crashes into a more severe and longer-lasting "low" mood, in my case.
I'm not currently on any medication. I tried Prozac once and it didn't help and indeed, side effects were pretty bad. I've never tried ADHD meds but I don't have much faith in them helping with this issue. Also I've had bad experiences from talking about my problems to both professionals and non-professionals. I may well regret writing this, but hey, it could help someone maybe.
Oh yeah, people often say things like, "everyone gets a little nervous around exams. In fact if you didn't have any anxiety, you might perform worse". Wrong! Or at least, from what I remember about the actual science, a little (repeat, little) anxiety might help a bit if the exam or performance involves a lot of physical activity and exertion. Otherwise, it doesn't help. I'd hate to think of someone worrying about the fact that they're not worried about an exam, because of this misinformation.
Things which might actually help. Be very careful who you talk to about this problem as chances are you'll just be invalidated and accused of not "preparing enough" or something. Or people might say, oh that exam is really easy, don't worry about it.
Try not to avoid or cancel an exam if possible, as this might train your amygdala (part of your brain that deals with fear, fight-or-flight responses etc.) that avoiding the exam is good and increase fear around the exam / exams in general.
Don't be in a rush to do an exam and get it done quickly, if possible. There is a place for "preparing" lol, but try and do it in a relaxed environment. As for driving, if I could go back in time I'd start by watching helpful (not anxiety-inducing) instructional videos about driving, reading about how cars work and so on (where I live most cars are manual / stick transmission, although that might be changing with modern cars). Learn how to do observations in mirrors and all that! Then find a good, relaxed instructor (be very fussy about instructors, change immediately if they're not helpful and don't bother with a particular instructor if you get a bad vibe off them when you call them or whatever). Some instructors allow you to apply online for lessons - this can be a good sign perhaps.
Some say that if you can spend time in the place where the exam is held, when nothing is going on, that can train your amygdala to learn that the exam isn't something to get really afraid of and avoid. This makes sense if possible. Also in some cases you may be able to do the exam in a small room instead of a big exam hall, if you ask.
Probably a long enough post already! Hope it helps.
