Is it silly of me to post it in my Instagram stories that its my birthday? Is it normal as i am hardly getting wishes by my peers?

Last year my peers(20s) and all wished me on my birthday when i was still in my MBA and posted it in my stories but this year except maybe 2 or 3, no one is wishing on me on Instagram really despite viewing my stories and all from my MBA same year, junior years and school days so kinda feeling invisible this year. Here are the screenshots of it so does it look silly?
