What am i?

Have been diabetic for around 17 years now and have been put on various insulins over this period, which non seemed to do their job. I am now on Novomix 30 combined with metformin 500mg 3x daily. I have been told that i am insulin resistance therefore this is one of the reasons i have put on so much weight.
I am also told by my Kidney consultant as well as my GP there is nothing i can do about the weight gain. I have asked about Bayetta and it was a definate no no as i was told yes i would loose the weight but through vomiting as one of the side affects of bayetta. I have rescently been diagnosed with neuropathy ( to no suprise) and investigations still pending. I live in Cyprus so my diet is very good and i do watch what i eat but just to look at a vegetable i seem to put weight on!!
I am constantly bloated very little bowl movement, i do take supplements to help me go but to no avail. I have now become a homing pigeon as i feel too embarrest to go out as people remark on how much weight i have put on. I do take various other meds for other health conditions but have been told they do not cause weight gain. I am however abouit to embark on a one to one training coach as i am of need of a booster when i comes to excersise so i am keeping my fingers cross. However are there any new drugs ie isulin or metformin that is available on the market in the Uk that i havent heard about? I was told metformin helps to loose weight but i dont see this happening?
Any advise?

Thank you both for your replies, much appreciated.
Although as mentioned its been 17 years that i have diabetes ive always been left confused as to my diagnosis hence my post. I tiltled it "What am I? " as doctors only rescently told me i was resistance to insulin and yet i still dont know what it actually means, and how is it my body works against the isulin im injecting is that why i am resistance? The metformin has somewhat reduced my appetite to the point i really dont have appetite to eat especially in the mornings, infact i will eat a descent lunch and after that i am quite happy not to eat anything at all after that the rest of the day. I was asked by GP's to take 2x 500 mg of metformin for the last 2 years, and only rescently been asked by the kidney consultant to up the dose after haveing a full blood anylisis and a GFR. In 2 months will have another bllod test. my Kidney consultant (UK) has diagnosed me with Known mutation of hepatocyte nuclear factor 1-beta, ( what ever that means) and Renal dysplasia with cysts and chronic kidney disease. yet doctors and kidney specialists in Cyprus insist that according to by blood tests results its not chronic! I am confused. With all the meds i am on i am within the limits for my kidneys apparently.
With regards to Bayetta i will again discuss with my doctors if it does cause me to vomit im sure it wont be for ever its still worth a try.
