I'm glad you are trying things and haven't given up!
Ok so to start I think the pump is a very useful tool and when used correctly will give you better control over your diabetes. With that said, the pump alone will not fix your problem because diabetes requires a certain lifestyle. I think it is important that you find the proper pump suited for you and the proper injection site to have your pump. I used OMNI POD on my abdomen the first time around and I had horrible results and despised it. Now I use OMNI POD but on the back of my arms and it works amazing and 99% of the time forget it is there.
As for the the eating problem you are having, this is all a mental battle we have (If I eat less I feel hungry) because we are so used to empty calories with no real nutritional value it takes long to break the habit once you train your body. As a type one we should be eliminating all processed foods so our body can process the food and not spike our sugars so high and for lengthy periods of time. We need to eat smaller portions of natural food every 4 hours and to make sure if these foods have carbs that they are on the LOW GI side. Sweet potatoes, brown rice, blueberries, a good cut of oats, lentils/beans, flax seeds, and hemp seeds, etc. Make sure protein is lean with minimal fat because unlike nut fat it will mess with your blood glucose.
You are living a sedentary lifestyle which imho is 100% the main reason why nothing you are doing is allowing you to control your diabetes and why the high blood sugars is causing anxiety. As a type 1 you are going to have to incorporate high intensity exercises into your day to increase your insulin sensitivity so that your blood glucose will stay and a much more moderate level after the 2 hour post meal spike.
I have personally been down the road of anxiety medication, depression medication and that experience showed me one very important thing. This medication is a bandaid for a problem that has a solution.
I guarantee once you start to change these things and incorporate what I am telling you, that in a week, 2 weeks, 4 weeks you will feel COMPLETELY different, feeling good and radiating once again.
If you have ANY and I mean any questions about this stuff, or want me to be more specific do not hesitate to ask because there is more than hope for you to feel good again, it is a guarantee!
