@KENNY I should not ask it but why did your mom turn into an alcoholic or was she an alcoholic from the start (before you were born) ?
The reason why i gave up on getting good grades was that my brain believed I should try less as much as possible in order to maintain an easy going lifestyle towards studying or any extra curricular activities (not the sports part ofc) this became a perverse pleasure i believe, trying too less in order to get okish results and if I fail i will have a reason to blame "I didnt even study for it". 

Be it any hardships you face in your house or in the social circle, I want to advise you to keep your clean behaviour, whatever you did before and naturally let it be. I think this will definitely take a toll on yourself due to the problems in your household, but i think you should make new friends but GOOD people or even somee unknown online friends, who should also be good people as its possible for a normal person to by mistake or intentionally turn and try to brain wash you.

Those people will be a means of social interaction for you and do not resort to ai for this as ai lacks humanity (the emotional feeling or more like the human errors). 
LIVE A GOOD LIFE, 
i am saying the following without giving any motivation for you to harm yourself, i promise.

LIVE YOUR LIFE, FOR THE SIBLINGS.
ONCE YOU ARE GONE, THEIR LIFE WILL FALL APART EVEN MORE,
be it the emotional toll on them for not helping the sister or their thoughts like "maybe its was my fault".
and read less manga and manhwas, instead study everything TO GROW , wait no.  just live
