I don't get it

Maribelle -- while asking your doctor is a good start in regards to therapy -- don't let it be your only path. A lot of doctors dismiss therapy or they themselves don't know where to start. If you are truly interested -- look around for someone that deals with eating issues or addiction issues. Sometimes local mental health clinics can point you in the right direction. Or call up your insurance and ask them for people whose specialities are these areas. Good Luck.
