I feel like I’m only other peoples perception of me.

I don’t really know how else to put it, but I feel like I’m living only through how other people see me. I’m always thinking about the next moment and how I’ll appear to others in that moment, for example, this week I traveled somewhere I’ve always wanted to go and instead of enjoying it I was posting and wanted to see other’s reactions. Maybe it’s a form of validation but I’m not even sure how to fix this but I know that it’s making me miserable. I can never stay grounded.
