Thanks for all the replies, I've just caught up on them all.
With regards to childhood trauma - I have a good childhood overall. I'm not sure I suffered from trauma in my younger years. My parents separated when I was a year old, argued a lot during that first year of my life and she said I could have suffered trauma from that, but I'm not convinced of that tbh. The only thing I could think that may of caused any childhood trauma was my older sister, she's 10 years older than me and was really mean to me and occasionally violent. When I was 14, I went through a traumatic experience, which I know has affected me through life, although I was already experiencing issues by this point. Other than my sisters behaviour towards me, any traumatic issues I encountered were past secondary school age.
The reason I'd like to know isn't for the label, as I said previously, it would be better if I didn't have it, for obvious reasons. I was happy with the outcome initially, it just plays on my mind a bit as every single thing I see/hear about adhd is me. And I'm just a bit of a weird/awkward person, there's other nuances, not just the big, obvious symptoms, which just fit me.
With regards to the reading, yes, it's like I become hyper focused with it. If I can't get into something, I can't follow it. But when I get into a book, I won't put it down until it's finished.
Some stuff just seemed so disregarded, like the fact that I've started about 10-15 courses in my life that I've been unable to finish, all wildly different from each other. They've all involved meltdowns infront of college teachers, late assignments, and stress until the point I quit. I managed to finish 2 of them, one was due to my tutor allowing me to finish at home with a lesser qualification, and one where my assignments were all done last minute in the 24 hours before they were due, I'd become so hyper focused that I actually felt like wired, my brain felt like it was operating on a different level. I get a similar feeling when I get really obsessed about something, an idea that I NEED to do now, and I talk about it non stop and feel a buzz as it's all I can think about for a while.
