can i have a mom rq?

If you’re a mom and have actual advice for me read this. it’s a lot but here it goes.

so i’m 16, and just recently my mom left us.

i live with my dad my little sister and my older brother. i have an older sister from my moms side, but she doesn’t live with us she’s grown has her own child, is finishing college, is a preschool teacher. my mom has already raised her.

growing up my dad was always gone 24/7 bc my mom as she claimed “was on disability so she couldn’t work” she has bipolar and border line personality disorder, she also had blood problems like clotting, which moved from her legs to her brain this past year, so i knew why she couldn’t get a job, she was too risky to be hired. (i thought)

i’m the middle child so i was use to not being the center of attention and i was perfectly fine with that bc i love being by myself and having peace and quiet. but my little sister was completely dependent on my mom growing up. she 14 now. still growing. we all are. this year my mom told us that she was diagnosed with colon cancer, for a while we tried to figure out how to help her , then she ultimately decided that she just wanted live out the rest of her days with us bc we didn’t have enough money for treatments. (i envied her selflessness). a few months later she got aggressive towards us all, she didn’t want to keep whole conversations with any of her children. we just thought she needed to cope with her fate. she started looking really sick. got super skinny, her eyes became sunken, she was throwing up everyday and anally bleeding. she started becoming more distant with my dad. she would disappear for days at a time. and my dad would always cover for her . but she ended up leaving longer, for weeks at a time. the last time she came back home was to tell us she wasn’t coming back. out whole family got into an argument with her. i just broke down. my littler sister depended on her so much and we were all still growing . i didn’t yell at my mom that night. i broke down crying , and when she was about to leave my room i said “if you walk out of that door you know he won’t let you come back. i won’t forgive you. you’re leaving your family for what ? because you’re sick? you want to feel better when we’re already here trying to help you?”, i remember everything i said bc this is the day i will never forget. she couldn’t look at me while i was talking which got me angry. so i continued, “if you walk out of that door, you’re not my mother and i’m not your daughter anymore.” that was the last i had said to her before moving out of her way. she left without saying anything to my little sister. i heard the last few words my parents said to each other.

my dad: you’re not just leaving me . you’re leaving our children. the only ppl in the world that love you.

my mom: d, i don’t care.

i heard the front door open and close behind her, i watched her walk to this black suv and get in the back driver seat. i heard the engine roar and for the first time in 10 years i heard my dad cry.

fast forward 4 months , this brings us to now. my mom has a job at walmart the same walmart as my older brother even thought she has “cancer, blood and mental disorders and she’s on disability.”

crazy right? . well my little sister was completely dependent on my mom, she doesn’t even want to talk to me, or look at me, or eat dinner with us. she’l was the happiest of us all now she’s depressed and sad and she’s made new “friends”.

today i was called down to our “genesis room” at school to be told that my 14 year old sister almost overdosed on xanax at 8am in the school bathroom . my dad took us to the hospital so he didn’t have to be charged with an ambulance fee. and they detoxed her.

the administration knows ab our home situation, and the vice principal looks at me all puffy eyes crying and says , “you can’t do this alone.” i looked at my sister and said ,”why? what the fuck would you do this?” her first answer was , “i didn’t want my friend to be alone.” i asked her again when my dad came to pick us up, she said “i miss mom. i’m just so sad.” i saw my dads heart break again. i looked the administrators, i looked at my dad then i looked at her. i told her, “you can’t depend on drugs to make you feel better. not about anything. that’s how you become a crackhead on the ave.” , she couldn’t even hold her head up that’s how fucked up she was . my brother took me home before going to work today. she’s still at the hospital. im pretty sure it’s gonna be a whole until she sits without pain. my dad is gonna whoop her. i’m the only female role model in this house and i dont know what i have to do to help her. she doesn’t want to listen to anyone.

i need help and advice . from any mom willing to take their time. please . i don’t know what to do.
