Hi. Back in September, I was told I needed glasses and got them. Even though I wear them for reading, I get a little bit of a blur when they're off. Knowing me, I'm not active, I'm pretty hungry all the time (I've always been like that since I was a kid), and i get itchy skin. The only thing that is new to me, is feeling tired and weak all the time. This has been going on for a few weeks now. Diabetes runs in the family and looking these symptoms up makes me think I might have diabetes. Should I be concerned?
