Expertise:  I can answer anything you throw at me. Although it has to do with this subject. For the drug and alchoholic friends, I can't do anything about that, but what I can do, is advise you on how to deal with it and some pointers if you want them to stop. Again, I can answer anything you throw at me!

Experience in the area
I have a LOT of friend issues of my own. Them yelling at each other, them trying to do everything and anything you do, ect, ect...To my family and most of my friends, I'm the drama queen and the who my friends come to on advice of anything. (mostly friend and boyfriend stuff, but that's a different experty of mine)

Education/Credentials
My educational credentials would be, my friends, my family, and often I look up advice on the internet that isn't always true. I learn from all of it and what not to do from the other internet sites.
