Is it possible to not have enough hormones?

Omg, I'm very similar to you. Yes I get cramps but my drive is so low, it's like I don't have one at all! :) It's actually a good thing, I guess since neither one of us will go out of control one day, if you know what I mean. And if you have a boyfriend, that's a plus, for being so controlled. I do too and so am I. About the gray hair, well that happened to my aunt when she was 19, she also has a fast metabolism and is skinny. She has a fast thyroid problem. I'm a bit different on that because I have a slow thyroid problem but I'm not fat at all, so I know where you're getting at. Don't worry. Even though a lot of it IS hormonal, it's nothing to be ashamed or worried about, because all of it has it's benefits :)
