Is it normal to not care about your birthday?
Yep.Totally normal
Yes, it’s totally normal not to care about your birthday. You don’t have to celebrate or feel any particular way about it.
Some people love the cake, attention, and excuse to gather; others would rather treat it like any other day. You might not enjoy being the center of attention, or birthdays may simply not feel meaningful to you—and that’s fine.
You can celebrate in a small way, skip it, or change your mind from year to year. There’s no birthday enthusiasm requirement, despite what the party balloons suggest.
