First of all, OP, can I just say that you were pretty rude to Bunthulhu when she was only trying to stop you doing something stupid, i.e. effectively getting a diagnosis of a load of random internet users. Not on really.
Secondly, that list of symptoms, as with lots of internet self diagnosis tools, is very vague and a lot of the things really could apply to anyone if you looked carefully enough. You say you're not a teenager run amok but in my experience that is what ADHD is - out of control behaviour. The person I know of my own age who has it has nights where she is totally wild, screaming, yelling, pulling her hair out, talking nonsense to her flatmates, breaking stuff etc etc. She is literally like somebody gone mad. You can't get any sense out of her and if you speak to her she is totally unable to follow the thread of what you're saying, much less grasp any kind of logic, and is generally impossible to calm down. She finds it incredibly embarrassing once she's returned to normal, but has literally no control over it. If that sounds like you, fair enough, but procrastinating, fidgeting, losing stuff, having a short attention span et al are just human traits that occur at different times according to tiredness, stress etc and more frequently for some people. ADHD is truly debilitating in terms of living a normal life.
Now I know you said you're not looking for a diagnosis but you are looking for people's opinions and I really don't think it's a good idea. Close the thread, or you'll just start getting unhelpful or worrying replies. If you are genuinely worried, go and see your GP.
