(I don’t know where to post this)

I’m 14 years old and I like to drink. Only because I feel stressed in my everyday life. My mom is alcoholic. She drinks almost everyday. Then she picks fights with me and tell me that I’m her least favorite child. I stay in my room and drink whatever drinks are leftover. I know this is bad at my age but Idk what to do now. I don’t do it all the time but I just wish I didn’t have to. I’m also seeing a therapist but not for my drinking. Idk what to do and I’m kinda scared because I don’t wanna be like her or have brain issues or something. Pls help
