My mom told me "you are good because I made you good"
Do you feel that you're good because of your mother?
No, and I am angry because of it and am going to destroy my aquarium full of fish because I think they are disgusting
You shouldn't hurt the fish because you feel angry at your mother. They are living creatures, even if you don't like them. You should think about finding someone else to take care of them instead.
Fuck you mother fucker, it is her fault that I turned out this way.
That doesn't make it okay to hurt animals. Even if your mother has hurt you or made you angry, it's best not to take your anger out on innocent others.
