The problem with all of this, in addition to the fact that it's not actually true and it dismisses our feelings, thoughts, and needs, is that it convinces us to bend well past the point that we should. When we try to stand up for ourselves, we're often told we're being difficult. Sometimes, if a person is really being unfair, they'll point out "how much they put up with" because of our condition. They'll point out how flexible they are for us, because of our condition, how much they accommodate us. And this may be true, and it should be acknowledged - but not as reason for making us back down and stop standing up for ourselves.
In every discussion, or almost every discussion, there is the opportunity for compromise. Sometimes, it's one person giving in one situation, and another giving in another situation. Sometimes you both adjust and meet in the middle. But when it comes to being treated the way you deserve, do not give in. It's easy to think of ourselves as too needy, as too much trouble, as a burden. It's easy to bend and bend, thinking we owe someone else for "putting up with us". It's easy to be convinced that we're asking for more than we deserve. Much of the time, though, I'm willing to bet that you're not. I'm willing to bet that you're selling yourself short, because others have always taught you to do so. I'm willing to bet that if anything, your condition is telling you that you deserve less than you actually do. I'm willing to bet you've bent so far at times, trying to compensate, just in case you really are being too needy or demanding. Just in case you really don't see things as they truly are, no matter how sure you are that you do.
And when we do this too much, we break. We break our spirit. We break our hearts, or others break them for us. We break our emotions, often turning numb because we've cared and given so much that we're completely drained. We're hollow. We can't feel. When this happens, know that you are not alone. There are others out there, like myself, who understand exactly how this feels. Who don't blame you. Who won't let you blame yourself. There are others out there who will stand up for you when you have bent and broken to the point that you no longer feel able to do so for yourself. And eventually, you'll get back up. You'll remember that it isn't all your fault. You'll know how much you deserve. One day, you'll be able to say, "No, this time, it's not me. It's you."
