I rarely post or comment because I become anxious about people who search through profile histories
Why would someone search through profile histories?
To see who reads posts and doesn't respond.
It's understandable to be anxious. If you don't feel comfortable with people seeing your post and comment history, you should make a private profile.
I get anxious. I don't want to make the post. I'm rethinking if I want to comment now.
It's okay to have anxiety on social media. Maybe you should be really selective about who you have in your social media circle so you can create a space that feels safe to you.
