Words hurt exactly as much as you care what whoever said them thinks of you. This leaves u with 2 cases.
Case 1: your friend whoes opinion u value is saying something hurtful, ask em to stop if they dont u dont have to be there friend or value their opinion.
Case 2: its some rando whoes opinion you dont value. The only reason u would care what they think is if your insecure.
So what is it? Words dont hurt? Your friends arnt actually ur friends? Or are u simply insecure?
