That is a choice you'd need to make... I'm tired of people telling me that I should exercise and go on a diet and do this or that or this new thing and then my problems will be miraculously cured. I avoid pregnant people if possible... And I avoid people who tell me to exercise and go on a diet too. I avoid situations where I'm going to comments about how I don't need to eat this, or are they sure that I should be buying that.
The only people who believe my exercise stats (the ones posted in my sig) are those that SEE me at the gym, and I think my endocriologist, and some really good friends who have known me for years and know that I don't particularly lie about a lot of things. Most people look at me and assume I'm lazy and mainline twinkies all day long. That isn't true. I lift weights daily, I swim a mile or more daily, and I also just started riding a stationary bike... That is harder because of the nerve damage in my ankle. It doesn't make much difference though: I haven't lost much weight, I don't ovulate correctly (ever), and never even bleed.
Its hard to deal with those looks or the comments. There are times I want to punch people or scream at them until they lose their predjudice. But that probably won't help. I don't like being that way either, but I'm not sure what the solution is.
