I didn’t get diagnosed until 49. It pretty much took my wife forcing me to go see a psychiatrist because she couldn’t take it any longer. I’m also pretty sure I’m on the ASD spectrum but I haven’t been diagnosed formally. I’m also constantly fighting with my insurance because I’m now 54 and “too old” for the meds.
I tried it several times and couldn’t get the hang of it. I’d always overshoot the character I was going for. I had a colleague who was amazingly fast with swiping to type.
