Call ended before I could finish the sentence

Call ended before I could finish the sentence Hello everyone, it's me again, I just tried to order some food from a restaurant for my family's dinner and the person on the other side of the phone ended the call when I started to have several blocks before the name of a dish (it was "rice", I have a problem with the R letter). I'm surely overthinking: she probably hung up the phone, because she thought I had poor connection or something, but I still feel sad and frustrated I also said to my brother that I wanted to make the call (I felt brave), so now I feel even more ashamed about myself even though he know it is a huge struggle for me. How do you deal with this type of situations?
