a fear or phobia
From what I understand there is no specific phobia for people who are afraid of mail. Most just call it Mail Phobia...
Phobias are an anxiety disorder in which someone's fear of something is extreme and irrational. The phobia of cockroaches is called katsaridaphobia.
I, suffering from this same phobia, had to come up with the word for it myself. I call it Invertophobia.
A phobia of small spaces is called claustrophobia.
It's hurtful to call someone names or make derogatory remarks about their character, appearance, or abilities. It's important to treat others with kindness and respect, even in moments of conflict or disagreement.
