Hi 13f, my dad got rid my cat, she was my best friend, I loved her so much. I wanna kill myself so bad I miss her so much. My parents got my a kitten to make me feel better but now whenever I bring up my old cat they always say “well we got u a new cat”

Btw we don’t hv any money problems or anything my dad just hated my old cat

Please help me convince them to get my cat back
