there are a lot of us here, supporting either parents and caregivers or fellow t1’s. The first year is tough. You will be an expert by 18 months so do not worry about learning everything at once.
the best reference in my opinion is “Think like a pancreas” which is a cheap buy on amazon and worth it’s weight in gold. the other thing helpful is the “Calorie King” book or online database for carb counts.
Check out the JDRF for a local chapter. Got to http://www.jdrf.org/ and click on JDRF NEAR YOU at the top.
I hope you have access to a Diabetes Educator, they can be most helpful in the beginning and often have more time to support you than an endocrinologist.
I have had this for going on 38 years, and so has a bunch of us here. Please reach out if you need support.
