I'm mad at my friend over a picture
Is it because of the picture she took of you?
Yes. I feel like she betrayed my trust and went behind my back.
You should talk to your friend about it and resolve your issues. I think she might be understanding if you let her know how uncomfortable you are with it.
Only losers care about something so stupid
You can call me all the names you want but if you still feel hurt it would be good to talk with her. She may be willing to delete the photo.
