One of the things that keeps me from suffering that anxiety is knowing that the intensity of our experience is never as intense externally as internally.

As for anxiety around being misunderstood, I've come to grips with that through successful therapy: experiencing the reality that I definitely will be misunderstood, BUT that we'll have the opportunity to work it out, it won't rupture the relationship beyond repair and I won't be abandoned for saying or doing something in a less than perfect way has been a good experience.

So, seeing that I have come across differently than I intended or acted uglier than I would have wanted, but finding that life goes on and it can be worked through well has been the simple key for me.
