I find there is a lot of invalidation given to self diagnosis. Diagnosis, especially of neurological conditions is practically impossible to get. I saw an article on the abc today that waitlist for specialist can exceed 5 years, especially in areas like neurology.
I was lucky enough to have a large amount of savings and got my formal asd and adhd diagnosis this year. I had long suspected asd and was oddly surprised with my adhd diagnosis, even though now I see how my adhd adversly effects me on a day to day basis.
Self diagnosis usually will lead people to help and understanding. It should guide us into an awareness of our difficulties and ways to work through them, not an excuse not to do something. I see the authors point about becoming a label, making it who we are, instead of a way to explain the help we may need and ways we differ from the norm.
I dont see the same arguments for self diagnosis of depression as self diagnosis of adhd in modern societ. But to me they are the same, why should we validate someone's self diagnosis of major depression without listening to someone who struggles with their attention and working memory. As long as both lead the person owning their struggles and finding ways to manage it. Both are chronic illness, and needs to be treated and managed.
I usually tell others, most medical diagnosis start with the patient saying this isnt right, or I struggle with xyz, they go to their doctor, who does some test, and gives diagnosis, then treatment and management. So why should a self diagnosis be invalidated, if it leads the person to help and support, especially if most cannot attain a formal diagnosis.
A diagnosis, self or otherwise, should lead a person to finding help and support tailored to their needs, it leads to greater understanding of one's self, and should help the navigate a better life post diagnosis.
Diagnosis arent our identity, and never should be. They can help explain why something is such a struggle, and as long as other arent an excuse, but an explanation i will always listen to when someone says they have a condition (physical, mental, emotional, etc) because if they identify with it, who am I tell them they are wrong. No one should fight to be acknowledged or heard.
Im lucky I fought so hard to be heard and receive my diagnosis, but it shouldn't be so hard to get acknowledged and heard about what I struggled with.
