I did the same, and then one day, the doctor noticed. We had a chat, was much easier to tell him after he noticed. Then did a couple of tests, spoke about options available..... and went from there really.I've known for well more than a decade and still haven't told a doctor. I have hoped anytime i've gone in for something unrelated one of them would notice and say something but it has never happened.
i've tried self-medicating throughout the years. Results weren't favorable. I Don't advise it.
