i feel so terrible...

so basically my mom is an addict and slipped up recently and it was bad and pissed me off so i had been keeping my distance and staying at my bfs house because if you’re a child of an addict you understand how draining it is. she just up and left for a few days and didn’t have her phone on which she doesn’t usually do when she has her times of using drugs. well she was home these past two weeks and like i said i wasn’t around because i was taking my space from her. turns out her phone has been dead since saturday so i decided to go to the house today because i was getting worried about her and possibly the cats like i always am ... turns out they probably haven’t eaten since saturday because they looked shaken up and sad and their bowl was dry but the cat food was on the floor bag ripped open so i assume they ate some of that ? i feel so angry and terrible because it’s animal neglect and abuse and i had no clue she was gone AGAIN because she decides that she’s gonna just leave and not charge her phone and not even bother to feed the cats... i feel so terrible i gave them so much food and water i just hope they’re not going to get sick or have health issues. my one cat is fatter than the other one but i am just so sick of what she’s putting us through.
