Welcome!
I was diagnosed pre-diabetic in November and I love this community!
In some ways being a Type 1 can be easier, in that you can adjust your insulin if you are eating more carbs. But, you also have the risk of lows. Still, it's not a big risk as long as you calculate your insulin, which will no doubt become second nature soon.
I agree that lowering carb intake will help a lot. My personal goal is 15-30g per snack and 50g max per meal. I don't really keep a daily total. The big thing for me was cutting out the "casual" carbs like soda, and paying attention to my meals to ensure they weren't carbfests. Pancakes for breakfast, for example, is not a good idea anymore. Make sausage too, and even better eggs, and maybe have one small pancake while eating mainly the meat and eggs. You don't have to give up sweet things altogether, but you need to pay attention to what you eat.
I realize now that although I wasn't consciously doing it, I was actually gravitating toward a low-fat, high carb diet before I was diagnosed. That means Twizzlers are OK, after all they're low fat and fat is evil, right? LOL. Low carb and high fat is a much better option for me, and maybe for you. Try different foods, keep testing with your meter, and see what you can eat.
180 is a bit high, I'd try to keep post-meal closer to 140. (For me, that's 7.8)
