How old are you and what was the reason you decided to be assessed for ADHD?
I'm 25. I've thought I had it ever since I heard about it a few years ago, but procrastinated doing anything about it. My final year of uni especially was such a struggle. I left every assignment (other than my dissertation) until the night before, and even then I couldn't concentrate on it - would sit on my sofa MNing feeling more and more anxious and stressed but I just couldn't bring myself to start and/or focus, even though I wanted to so badly. I began to realise that there was no way this was just a quirky neurotypical way of behaviour. I didn't achieve what I could have done grade wise, and I want to do further study equivalent to doctorate level, which I could never do with these symptoms.
I do have a lot of symptoms at work, at home, as a parent, in relationships etc. too, which I'm hoping will also improve with treatment. But these symptoms weren't tangible; I just explained them away as being lazy, useless, disorganised and irresponsible (which has had a rubbish effect on my MH).
