Hi Carrie, welcome to the Diabetes forum. I'm sorry you've been through the mill with the flu and all. Yes, your blood tests are out of range for normal blood sugar. You've lost 20 lbs in the last 6 weeks but was that because of being sick? Or, could it be related to diabetes? Maybe. Your other symptoms could also be related to diabetes in some way, either high or low blood sugar. So it seems to me it's a puzzle and I would suspect that your doctor would need another blood test or two to determine if you are type 2 or becoming a type 1.
As a type 1, a person doesn't make his own insulin anymore and needs insulin shots. As a type 2, a person still makes his own insulin though maybe not as much as before and will probably start on oral medication and a change in diet and lifestyle if needed. Both types benefit from a low carb diet and more physical exercise. Low-carb doesn't mean no carb. It does mean cutting back on all bread, other flour products, rice, potatoes, anything made with sugar (or honey). You would be testing your own blood sugar with a meter when you get up in the morning, before a meal and a couple of hours after a meal to see how your blood sugar reacts to the food you eat. This is why keeping a daily log of your food and activity (with time, amount, etc.) is important.
Being 5'3" and 125lbs doesn't fit the type 2 image since that 'type' would be overweight. However, a type 1 might be losing weight for no reason and people do become type 1 later in life, not just as children, so this is one reason to ask why you lost the weight. To determine if your pancreas is still producing insulin, you might have a blood test called the c-peptide. This shows how much insulin is being made, if any, and it might be ordered if there's any doubt about your being a type 1 or type 2. Another type is now called 1.5 or LADA which is when a type 2 slowly becomes a type 1. These tests are important to know if you're producing insulin so the doctor knows the best treatment.
So, be proactive when you see the doctor tomorrow and ask about what tests you took and should take and how he knows which type you are. Ask why he thinks you lost so much weight - was it from being sick for could it be related to diabetes.
If your depression, tiredness, etc. is related to blood sugar (either high or low), you can help yourself by eating balanced meals, not skipping any meals, eating a portion of protein and vegetables at each meal and keeping away from high sugar and high carb snacks - all this is in trying to keep your blood sugar levels even. (And if you think about it, it's how we have always told our kids to eat!) Unfortunately, lots of snacks and drinks have plenty of sugar content and this can really throw your blood sugar off with both highs and lows, producing shakiness and fatigue.

And here are some questions related to type 2 prediction: Are you overweight? Are you sedentary? Do you eat a lot of carbs? Are there family members with type 2? Did you have gestational diabetes?
Let us know how everything goes with the doctor. I understand there will be lots of questions and I hope you can find answers here!
