Laughing then crying.

So just yesterday my dad was yelling at me about grades (I had a D and F in my best subject,) and he got so mad he kicked a plastic bucket into the hallway and it broke into shards, before asking me what the hell my problem was. I instantly broke into a hysterical fit of laughter that I couldn't control, my chest felt fluttery and I couldn't think, then I just busted into tears before quickly wiping them away and stopping.
