My friend, please remember that as your body goes through all this shit — your mind will too. Having the machine mess with your BG levels affects your mood. Going low can do as much damage as going high, believe me.
Starting my senior year in college and going on for about 15 years, I was a diagnosed hypoglycemic. One of the ways Bruce would know my blood sugar was low? I would swap from griping and mad to crying and back in just moments. A few grams of protein later and my mood would stabilize again.
It’s hard to reach out to the world when you don’t know if you are going to feel the same way in five minutes that you do now. Covering the changes becomes second nature — not a good thing. Tell your therapist and your endo what is going on emotionally. Let them help. Remember too that we are all out here pulling for you.
