Could seroquel be to blame for my diagnosis of type 2 diabetes?

I took seroquel for about a year for bipolar disorder when I was 16. other than bipolar I was a normal healthy male. I'm 21 now and last year I was exhibiting classic diabetic symptoms and officially diagnosed with type 2 diabetes. I have two known diabetics in my family (deceased grandfather and then an aunt). I have reason to believe seroquel may have caused my type 2 as explained by a warning infomercial. I am skinny 5'9 145lbs and my readings go as high as 350-400 sometimes. what do you think?
