i have an appt with the surgeon today

I dont know what to expect, i feel like such a failure. i have been doing all the right stuff. exercise. water. protein. and nothing, nadda. i am just staying the same weight. i even got a prescription for diet pills and still nothing. my thyroid was tested and it is low, but at the low end of normal. am i doomed to always be this fat>? i really thought this tool would help me attain a normal weight. i am not asking to be 130 lbs. i just want to be the 100's . has anyone else had this problem? my husband is afraid for me to get the revision. he says it is too dangerous. any thoughts, comments?
