When to Tell?

How long do I have to know someone for before I confess what is going on, especially when I can't even tell my parents? Will it be a feeling? A moment? A knowing that'll tell me when it's time?

It probably is necessary to get it out because one of my fears is that the new person will catch me in a moment. Completely naked, stripped down and bare. I'm not saying I have to tell them everything at first. But at least inform them so when I am immobilized with fear, probably from something they've done, it's only fair if they don't think my reaction is to or because of them.

Am I telling them for me or for them? I...crap, fine I'll admit it. (It could be logically wrong to all of you, maybe someday it will be to me.) I'd rather they know sooner in case they get weirded out by it and think I'm crazy. Offer them a way out before we get to know eachother too much. In case their reaction hurts. I mean, how much more can one person go through?

I am constantly heavy hearted around those who I'm hiding it from. It's a big weight to carry around and it tires me out.
