Hi Emalina,
Totally understand what a burden diabetes is and how it can drag you down!
Everyone finds their own way of dealing with diabetes but here's my advice: try to dissociate it from yourself. Treat it as a bunch of numbers you're interested in, not something that you care about. The emotional involvement, the worry, the guilt, aren't worth it. They'll damage your health more than slightly high blood sugars.
The better you are at self-adjusting your dosages the quicker you can correct situations like this. The last few days I've been getting hypos a couple of hours after many meals and then my sugars would shoot up high later. I've increased my long-acting (Lantus) and decreased my rapid somewhat and it seemed to fix the problem. If you can confidently make that kind of change on your own you're better equipped for life with diabetes.
