Newly Diagnosed College Student (T1D) :'(

Greetings r/diabetes.

This is my first post here and I guess I'm just looking for some helpful info, and/or any words of encouragement would be greatly appreciated.

I am a senior in college and I just found out this summer that I have T1D. I guess what I'm scared the most is the life expectancy and complications from this. I read online that our lives are shortened by 12 years, plus a bunch of complications in our kidneys, heart, vision... Does this apply to everyone with T1D regardless of how we take care of ourselves? I'm still trying to process all this, it's so overwhelming.

I'm 5'4 and 115 lbs and always have been pretty healthy; but I do like to eat ice cream/pancakes/cookies etc etc. Does T1D mean that I can no longer eat as many carbs as I used to, or just that I have to be able to match them with my insulin pretty well? Did you guys have to do (or suggest) any major diet changes?

Thank you in advance for any helpful tips.
