Mom went mad today

She screamed at me and screamed at the cat and shooed the cat away.

Idk what's wrong with her. I was so upset that I crawled into bed and took a nap. I just woke up 3 hours later and I still have no energy. I feel so exhausted. Like she screamed the life out of me. I want to cry. I'm so anxious. And I'm scared of her.

I want to take the cat to the vet. But she's threatened me.

When will I be brave?
