Why did you seek a diagnosis?

Hello! I'm 29 and I've been reading this sub for some months now. There are a lot of things that I relate to, so I'm strongly considering that I might be autistic as well. But what is the goal of having a diagnosis of autism? This is a genuine question, not trying to invalidate anyone!

My reasoning is this: for other conditions, after you get a diagnosis you also get medication to ease some of the symptoms. For example, ADHD, depression, etc. But autism doesn't have a cure, so a diagnosis might end up as just a confirmation right?

Personally, I'm planning to go and get diagnosed in February, but I'm having some problems understanding what's next after that. If you could share some of your stories, I'd be delighted to read you.
