Pre Symptoms

Well for the record, I have 3 months to move my ass into gear otherwise I'm lining myself up for diabetes.  I'm gutted and a tad miffed at what to do, yet I had all the symptoms to pre warn me before hand and what do I do? Nothing!! So here I am laying it on the line, telling the world that I'm morbidly obese and I'm lining myself up to die.  Like literally, I sat on the bus feeling worse than I did pregnant and I'm angry and sad at myself for failing my body and listening to the words that just don't work and I knew that in the beginning.  I can blame my OH and blame this and that, but I need to take the responsibility myself and do something.  Help is what I need, I need the help of someone who isn't involved personally in my life and can tell me the honest truth.  Where do I start.
