What would you do. is this person a threat to me? forgive or not?

look. you're no doctor, nor are you a psychiatrist. we don't know what's wrong w/ your friend. everyone is blaming their craziness on all odd illnesses these days. stay away from crazy people. there's a reason they are called that and one thing that's most known is that THEY don't even know what they're capable of any given day or moment. now that's some scary ****! pray for the girl and move on
