I have Chiron, virgo, 7th house & I don't have a lot of friends...but I find myself as a counselor or guide to them. I've read a bit about 7th house Chiron, & I've found people have had similar experiences of feeling like people unable to help/heal you in the ways you have helped them.
I've had a few friends in the past whom have changed drastically good after they met me. I think we have a stronger intuitive understanding to healing than others, therefore no one can help us, they don't know how...
I've come to learn I can only heal myself & the best that anyone can offer is their support & acceptance through my own sufferings...
