Are people more honest when you get into a heated argument? I felt hurt?

I felt hurt about something my cousin did and confronted her about it.. but I also offered forgiveness and said it was fine. It ended up turning into a horrible argument.

and then my cousin said that no one likes being around you bc you’re so slow

that really really hurt.. bc I feel like it’s true. I’ve been called dumb and slow my whole life.. it made me even more insecure
