"I had did it already". Hm-hmm-hmm. That is really a common one, too, just like "I seen her walking her dog".
Carol, I think "went missing" is correct, because saying "I got missing" sounds really silly and so does, "I went lost" rather than "got lost". Yes, you have been on a roll!
It's fun and I literally had to look up my state to see if it had an "autistic program". (It doesn't, but we DO have lots of programs "for" autistic children. LOL
