so i 18f have 3 sisters , 17f , 12f , and 7f , and my mom clearly has favourtism over 17f and 7f , its getting to the point where its fustrating I'm trying to be understanding but my mom Is literally making it impossible , my mom likes to take our devices from us randomly ( by us I mean me and 12f) while the other two don't have to deal with the same thing , also I feel like its important to know that my mom has pretty extreme mood swings and anger issues so I never really know what I'm dealing with so I try my best too avoid her but she still finds things to nit pick on me nonetheless , her and 17f love to gang up on me all the time by constantly critising me and love to remind me of my failures ( like bad grades and stuff) , my sister 12f has been getting the worst of it lately with my mom ALWAYS trying to find something wrong with her , if she doesn't find a problem she'll make one , that's just who she is , the thing is I feel so conflicted cause we geniunly have good moments too but she makes sure to make those not last too long.... a couple of weeks ago she threatened to leave my dad and me and my sisters and she packed a bag and bought a plane ticket and everything , I decided to ignore her cause Ive been dealing with her tantrums all my life and could literally not muster up the energy to do anything about it , and ofc she wasn't really gonna leave it was all for attention , during this time of me literally not speaking unless spoken to she took it upon herself to continuously insult and say really hurtful stuff towards me every moment she could , I tried my best to stay silent while only defending myself when absoultly necessary ,,,idk I'm just really tired of her and I'm really drained , its been affecting me my whole life , I remember being in year 5 and actually wanting to die because of how bad it got ..I'm not in a position to leave but idk what to do until I can...
