Holy shit I just got this huge responsibility

My job just trensferred me to suddenly being responsible for managing the blood sugar levels of a diabetic 5-year-old. Not without instruction, and I have been doing fine so far, but this is absolutely terrifying because it is so important. I think I can do this, but it is so scary. I'm experiencing whatever the opposite of alienation from your work is right now. It's actually an amazing feeling. Still terrified though.
