herbs for fear?

My 15yr. old son suffers from a lot of fear. Not fear of everything, he can function perfectly,- but he carries around with him a great deal of fear. Fear of what he looks like to others, fear of what's happening in the world today, he's afraid that his bad dreams will come true, - just a bunch of things, but it's WAY overdone! I mean, he really gets undone! I spend a lot of time with him trying to reassure him about himself, and life. I always try to give him self confidence, and always have, but he has always been a fearful person. I don't know what to do here. I'm not going to have him take some of this medication they offer today for Depression or whatever. Is there any type of herb that can help? I would greatly appreciate any help! thanks! Tweet
