Not me, but my BFF managed to get diagnosed in her mid-30s. She was killing her heart with all the stimulants she was taking and her other ways to cope. I don't k own hoe she got diagnosed, but she definitely didn't do it for thousands of dollars. She couldn't have afforded that.
I do know that therapy and medication made it night and day for her. She immediately dropped all caffeine. Her sleep and general mood was so much better and she wad way less flakey. She doesn't dismiss therapy although I know she hasn't gone every week for a while not and mostly goes when she's feeling like she needs it. Medication was a trip and error, but she's much happier with this steady state.
