I'm 53 now and was considering getting an official diagnosis a few years ago, I even had the initial appointments set up.
I canceled it, because there was too much going on in my life at that moment (even got a notification I could reschedule for later)
All that made me think about what I was hoping for from diagnosis. In the end it was just having something in writing that would help me with self-acceptance.
Around that time I also was in a group psychotherapy so I talked about that and that part is now solved.
Regarding meds - I don't want to try them now as my other coping strategies are good enough at the moment and I'm a bit wary of side effects as I need to take a handful of. medicine every day, anyways.
In the end you need to decide why you want a diagnosis. If you want to try meds I'd go for it. (My son "inherited" it from me and had meds for a time, which really helped him).
In a case like mine where I didn't expect any new strategies out of it or didn't want meds - it was probably the right decision to skip it.
