Hi LJ
Welcome to the forum,
Well done on the 20lbs. Excellent.
You say you are high protein, I'm reading into that you're low carbing.
Quite a few people mention sweating, dizzyness etc when they first start low carbing - sometimes referred to as Atkins Flu.
Re the panic attacks and lonliness, not heard anyone mention this, although depression is very commonly linked with diabetes.
You mention a lot of life changes, perhaps the changes are more of the issue? You've come to a great place for sharing experiences.
