I'm dying to say it but I can't

I'm dying to say it, but I can't, because I'm afraid of hurting anybody's feelings. This is suck. I'm such a terrible person. Should I sacrifice myself and my feelings so I won't hurt anybody. Maybe that's the best way then since nobody can read the sign except myself, so of course no one will understand. Moreover you, who never understand anything. Should I keep my mouth shut though my heart feels like screaming?

"My heart is not in it anymore..."
