Your post brought up a lot of pent-up stuff that I hadn't been aware of for the longest time...
I have Chiron in the 11th and when I look back, all I can see is disapointments with friends, backstabbing and just...
Horrible stuff. I usually never pay attention to Chiron, because there are bigger asteroids out there and I think a lot of people try to give it more importance than needed, but in this case, the wound really is in the 11th house.
Im at a point in my life (and Im still young) that I don't even bother with friendship anymore.
That's how wounded I seem to be. (I can't believe Im only realising this now, but it's all thanks to your post!)
@Cafeastrology about Chiron in the 11th house is mentioned:
"fear of crowds or groups." Boy, oh boy. Very true.
&
"In the eleventh house, it may indicate rejection from peers because of being 'different'." <- The story of MY life!
Some other interpretations that I found:
Chiron in Aquarius or the Eleventh House: These folks may seem utterly other-worldly. They may be drawn to technology in order to feel comfortable, safe and accepted. They may avoid social interaction and feel uncomfortable in large groups of people, mainly because of peer problems in their youth, or because they seem odd or different to their peers. Social rejection makes them withdraw into only those groups of people who share their interests and concerns, and they currently find great comfort in the opportunities provided by the Internet.

Chiron in 11th:
In this house the crisis of Chironic awareness has to do with the possibility of playing a unique role in your culture. It is imperative to give your gift, and Chiron's influence is to push you to develop your creativity and idealism. You are probably very individualistic or eccentric and have a sense of a great personal destiny. The key to fulfilling it is to release it from the hold of ego and understand that the universal energy flows when you are willing to be a conduit and not try to own it.
