feeling defeated and alone

Every mom and child fight, it’s natural. However whenever my mom and I fight she won’t speak to me for weeks sometimes months and it’s getting to the point where I’m breaking down emotionally. Names are being called and right now I just need my moms support. I’m so envious of families that bounce right back after fights. Aren’t we supposed to be there for each other?? How can you go months without talking to your kid especially when you know they need you. My moms threatening to take my dog away because she knows that’s the only thing that’ll really hurt me and I’m scared to go to school everyday because in the back of my mind I’m thinking I’ll come home to my dog gone. I’m breaking down and I don’t know what to do. My heart hurts
