Bloo, first of all don't be ashamed. You have nothing to be ashamed of.

My diagnosis felt like the fog clearing finally. I'm 37 and found out a year ago.

Don't tell your boss. My therapist doesn't recommend this. He says that they might use it against you like over managing you or not giving you more work because she/he might not think you can handle it.

This is your private matter. Hope this helps
