Can I jump in please?
I only began to suspect I have ADHD in the last couple of years when I have been reading into ASD/ADHD as my son has struggled all through school. He's late teens now and bounced around several different schools throughout his education 
His symptoms are unable to sit still and focus, no interest in drawing or reading, not even playing with toys. At the age of 6 he would hyper focus on computer games and that was our relief.
By age 4 he was horrendous and difficult to manage. Inappropriate behaviour at school, sensory seeking behaviour, no sense of fear, blurting out in school, butting in at home. Couldn't stop talking. (Shouting)
As he got older all schools said it wasn't adhd it was just him choosing bad behaviour.
By high school his anxiety was through the roof. He didn't understand what he was meant to be doing a lot of the time and fell behind. Teachers assumed this was laziness.
I looking into possibilities for his behaviour I came across adhd in women and was absolutely knocked sideways by the description of how it feels and mentally it went tick, tick, tick.
At school I was the opposite of my son, I was so quiet and anxious I barely spoke a word. I would explode at home though with outbursts of rage and violence. Things that would trigger me were being unable to find things or my sister making a mess in our room. I couldn't handle things being disorganised and messy. I now know I had selective mutism, unable to talk to teachers and would cry if picked out to answer questions.
With friends and siblings I was wild and fun.
At nights I struggled to fall asleep and I remember my mother having to take the ticking clock out of my room as it kept me awake. I teeth grinded and have done so my whole life, even now in my forties and my teeth are a mess.
I have chronic anxiety but my mind races and whirs 10000miles an hour.
I struggle with following detailed instructions, for example I struggle to cook as I've never learned to follow a recipe. I get through life by the seat of my pants, winging it. I have a reasonably high IQ but failed all my exams at school.
I didn't take anything in and couldn't study. I am a very visual learner and learn by doing, almost self taught. I have always been sensitive and emotional. I fly off the handle quickly and over-react, I still do this.
These character traits obviously made me unpopular with my family members and I remember being bullied by my parents and called obnoxious and various other things. I always felt unloved and unliked, this has caused ongoing MH problems in adulthood which were polarised in my pregnancy and birth of my son.
I'm at the point now where I live my life in a fog of anxiety fear and isolation. I have job hopped and house hopped, unable to stick at one thing or in one place. This has taken its toll socially too as I keep breaking up connections I make by moving on.
I had a very high pain threshold as a child, for example I pierced my own ears with no fear or tears.
As a teenager I reacted severely to very small amounts of alcohol and turned into an absolute maniac. I would do dangerous stuff like run on railway tracks, run on motorways, dangle out of high windows I even fell off a cliff onto rocks.
I would sometimes be aggressive and start fights with people or Id be completely shameless and hook up with any boy and end up in bed with them.
In every instance I'd have absolutely zero recollection of it the following day. The black outs were filled in by my long suffering friend.
As I have got older I really cringe at my behaviour and it's only now I can see I wasn't normal.
Other things I can remember is that I was very creative and was excellent at art as a child. I had very good grasp of perspective that was advanced for my age. As an adult my strengths are thinking fast on my feet and thinking outside the box.
I am a natural problem solver and do best when I'm playing a role. I amaze my dh by my ability to think differently, I always thought it was him lacking in brain cells but I now see I have a gifted way of thinking that not every one else has.
Now, in my forties I have no relationship with my family. Things have always been difficult and my parents were very cold and unsupportive of me emotionally. I'm not sure that seeking any diagnosis would help me. I do think my father is ASD, he was very difficult to live with, my mother has already said she doesn't want to read into it.
None of my family believed my son had adhd either.
Can anyone relate to anything I've written? I have a need just now to feel validated and feel I need to know my behaviour wasn't my fault
