Feeling like a failure

I've been taking the Metformin for 5 months now and I have lost 5-10 pounds depending on the day. I'm to the point of major frustration! I have been keeping in contact with the RE through e-mail so I sent them a message. And it basically said, "You help us or we will find someone who will". This message received a quick response and we have an appointment set up for March 16th. They said that when we see them we will come up with a plan. Okay, I can live with this, at least we are doing something.
