Without wanting to derail the thread, how did those of you who were diagnosed later in life get on prior to diagnosis? Did you manage to maintain fairly 'normal' lives?
I ask because I've always suspected I'm 'on the spectrum' in some ways. I was diagnosed with dyspraxia and ADD quite late (just before secondary school) but am a little sceptical of my diagnosis at times. Most dyspraxic people have poor coordination but I wasn't bad at boxing and kickboxing and, perhaps more tellingly, I was a truck driver for several years, working around the city centre - I was very good at reversing into tight spaces in the dark with literally inches on either side, whilst many dyspraxic people struggle to drive a car.
Amongst many other things, I'm extremely obsessive/compulsive, have sensory/textural issues, and used to have lots of weird quirks. I know it sounds daft but I went through phases of being compelled to touch my eyeball with my finger for no apparent reason and couldn't shake the impulse until I'd done it. One of many odd fixations.
I also spent years counting the words in sentences and the lines in a paragraph etc, and still sometimes do with subtitles. I'm also extremely singularly focused at times and if I'm about to make a point and the conversation changes I feel really compelled to steer it back so I can make that minor point, for seemingly no reason. I'm actually good with social interaction but it's absolutely a learned behaviour and it's almost like a multiple choice exercise where I have loads of openers and also things to fall back on if conversation dries up etc (although this is probably typical of most people to some degree).
I seem to have abnormally strong empathy (in terms of not wanting to upset others) but it's absolutely not from fear of confrontation and I can be extremely stubborn or even aggressive in situations where I'm 100% certain somebody is being a dick, but I tend to be very black and white and I find it hard to actually dislike somebody once I've decide they're 'one of the good ones' even if I witness them being a knob (this is hard to explain, it's like I know rationally they're not a nice person but I find it hard not to 'accept' their faults as part of their greater self).
Another thing is that I'm extremely literal. I used to find it hard to tell when people were joking. I actually have a pretty dry and somewhat perverse sense of humour for the large part, but I'm left pretty cold by 99% of comedy. I'm also really good at reading and had a reading age in the late teens shortly before the age of ten, but I just can't seem to compute things like cryptic crosswords.
Sorry, I'm waffling now but this is something I keep wondering about. I'm not sure whether it would make any practical difference knowing but I've been reading dyspraxia forums lately and I'm a little sceptical that I fit that mould.
