Am i overthinking it?

Ok to start of today is my birthday i have 5 friends and 2 of those fives know's my birthday since we've been friends together for 7 years and i was lowkey expecting them to greet me but they didn't so i just thought they might've forgot it so i posted on my story a picture of me and my family eating lunch with a cake that had a word written happy birthday on it then like 3 hours later i opened the one that i posted and saw that one of my friend viewed the damn story but nun happened oml am i just overthinking it? i'd like to think tha i am since the world doesn't revolves around me and theres more serious sit happening around the world, though i am sad since everytime one of our friend had a birthday all of us would greet them but then when its my turn the gc just be try as hell
