Then you quite possibly have it. One of the difficulties with diagnosis is often, and especially in the past, that people were reportedly compared to the typically disruptive boys who could not sit still or perform tasks at all, and if you weren’t one of them then apparently you didn’t have it. Nowadays it’s more recognised (but still has a long way to go) that not all people with ADHD present like that, and often (but not always) females present differently compared to that male stereotype. (For the record males too can differ from that stereotype.)

The two biggest limiting factors for diagnosis and treatment these days are seeing the specialist: 1) the time and 2) the money that go with assessing and finding the right treatment (should someone decide with their psychiatrist to go down that path.). This is where talking with family and friends, researching, and talking with your GP or psychologist can also help, to help you find the right decision for you. And if you have a diagnosis but are confused about whether or not medication is a good idea, sometimes a leap of faith (also called a trial of medication) will be useful. Maybe with a diary beforehand so you can compare your thoughts and feelings off medications and then on medications.

I hope, whichever path you take, you find the help and solace you need 👍
