I was just diagnosed with type 2 last Tuesday. My fasting sugar was 278 and my A1C is 11.5. I realized right away how dire my situation is so I have immediately eliminated all starch and sugar and drastically reduce total carbohydrate intake. That, along with basal insulin, metformin and another oral medicine (I forget which), and I just tested at 130.
Your doctor should really be helping you get started, you need a glucometer and testing supplies. The doctor can write you a prescription that will help with insurance. Your doctor should also be giving you a treatment plan and prescriptions for medications to help control your blood sugar. If he/she isn't, find a doctor who will.
100 is normal for sugar level
Good advice from Ray
All carbohydrates (carbs) turn to BG (blood sugar) you can start by reducing the carbs you eat.
and try Googleing "eat to your meter"
Diabetes is controllable.
