Mhm I think the diagnosis is mainly for yourself to have closure. Now you can better understand why and maybe you'll learn some tricks from autism communities to make life better.
You don't need to tell anyone. You can, but if there's no good reason, you don't have to.
Sometimes it makes social life or work life easier because people start to understand you better, but this only applies if it's an issue.
You can be happy you figured yourself out a bit better and you got a new club of people you probably fit in with :)
Congrats on getting the diagnosis!
May the textures feel comfy, may your relationships with people be smoother, and may you have fulfilling special interests!
Here's your obligatory cozy cottage, and may the odds be ever in your favor :)
