Welcome to the EC. Yes there is a great deal of knowledge that has been shared here.
A timely request for a book recommendation. I have been a member here for nearly four years so I hope the moderators will forgive me sharing my first book "Thriving As An Empath: Empowering Your Highly Sensitive Self" co-authored with a friend. We published just in the last couple of weeks. More information at http://empathcommunity.eliselebeau.com/group/thetootyourownhorngroup/forum/topics/thriving-as-an-empath-the-book
Keep asking questions here. You are among friends and there are many helpers in the community!
