Hi jenyki25, welcome to the forums! About those stomach issues, I'm not familiar with the problem as related to diabetes, but I wanted to pass one one idea to look at:
Gastroparesis
As for the rest of it, I recommend you read a lot of the threads, go into more detail about what you do to manage your diabetes, (you can be as broad or specific as you like) and what difficulties you have controlling your BG. Spend some time on it, you'll find much information, leads to information, answers, feedback here, but you need to be doing some grunt work yourself - get reading, and posting. I bet that there are better, practical answers out there for trips and tactics you can use to do better than an a1c of 10, even if you are a case of brittle or harder to control diabetes.
