I don't know how to start!

I have been having some medical issues lately.  We don't know what it is slowly checking things off the list of possibilities.  I honestly feel that the problem is weight related.  I want to lose weight!  I was losing weight and then I had a bad few weeks and my surgery. Before I knew it I had gained back 9lbs of the 20 something I have lost. My doctor was none to happy about it!  She told me I have to get my sugar under control. I told her I want to have Weight loss surgery and she is all for it...... she will do whatever it takes to help me get it done, but I don't know where to start.  I know my insurance has started to pay for the surgery but I don't know how to start.  How long is it going to take!  What is my first move.

Any of you WLS ladies out there have advice for me.  I can't afford to pay for the surgery myself so I have to find a way.  HELP!!!
