Hi Shannonsparkle, welcome to the forum 🙂 I think we all feel like this at some time or another, it's very difficult living with something that you have to make so many decisions about every day - sometimes it becomes overwhelming. What insulin regime are you on, and how are your levels generally? Fluctuating or high levels will have a big, and often depressive, effect on your moods. Might be worth having a chat with your DSN about how you are feeling, as they are often very good listeners and he/she might be able to help you formulate a plan to take control.
What are the main things that upset you about diabetes? You will find lots of people here who understand, so please feel free to tell us about your concerns 🙂
