Mom discouraged me about this disease

so im 34f recently diagnosed as type 1. when i told my mom that im now type 1 diabetic she freaked out started to cry and started doing research on this disease. she started seeing this documentary on youtube about sugar spikes and she came to me and said “ im sorry to tell u this but the lady that i saw on youtube said every time your sugar spikes your organs are browning inside” pretty much your dying slowly/ killing ur organs. i was like okay, in my head i was thinking how does this help me in anyway? people who are non diabetic also have sugar spikes so are we all just slowly killing ourselves? what do you tell me then about a young child who is diagnosed at 3 years old? are they not going to make live past 20 years old? pretty much i just stopped her and not let her keep on telling me anything more about the youtube video. am i overthinking?
