Lomax,
You're far from being alone being born in such a "condition".
Based on an observation of a few posts I've seen from you since I joined the forums, I'd say a strong yes.
You are torn between wanting/needing to speak out your truths, but at the same time you do not want to hurt anyone. Because others matter to you.
I'm telling you, there is an in-between. You can be honest, it doesn't necessarily mean ruthless ! Even in nowadays' society. I think you have interesting things to say, if you don't hold back. It would be something like this, if you have something to say, that would probably hurt someone, don't you have a way to show to that person ? So that they get on a recovery path, I mean.
I never heard of a jaw chakra. That doesn't mean it doesn't exist, maybe you're onto something.
As for the chin, I often have the same feeling. My most spiritual and sage advice is the following :
Change your shaving cream !
Be well
