I do this all the time and it drives my husband nuts. I'm usually totally off too but I can't help researching ailments and symptoms on the internet! Already this year, I was convinced I had thyroid cancer and restless leg syndrome. And this weekend, I was 99% convinced my son was on the autism spectrum because he clicked his tongue when I asked him to say "SIX!". My friend who works with autistic kids (yes, I called her) was cracking up when I told her. She said "You're teaching him the word six? That's hard for a toddler who's just learning to talk? Teach him Ball or Dog!"

Do you ever self-diagnose? Are you usually wrong or right?
