Prepartam depression

Hi there, im going to see my doctor monday as I suspect I have it. I feel absolutely ridiculous if I do as I know how lucky I am to be pregnant. But the last month has been awful. I havent left the house except for work. I have no energy or desire to do anything. My house work and my appearance are suffering because I simply dont care. I only eat because I have yo. My anxiety has started again. Im sleeping constantly. And generally just feeling like crap. Just wanting to get opinions thanks :)
