My mom is drunk again...

So my mom has been to some party (or whatever) and she got drunk and my Grandma has to yell at my drunk mom and this shit has happened every single motherfucking time like I love my mom but come on! Why! Ones at my friend's house then after another visit to friend's house and my Grandma is angry at my mom! I hate my life, and of course my mom when drunk does not answer phone calls or anything and in house I have to listen to my Grandma yelling and my drunk mom listening to music at loud and I remember when my mom turned off wifi while drunk and I couldn't do anything because I was on my tablet with no mobile data! 

I hate living like this why did I allow my mom go to that fucking party! I HATE MYSELF!!!!

P.s please do not send police or anything to my mom she does not abuse me when drunk or anything like that just lays on bed drunk and my Grandma is angry!
