Bro, Don't. Even your mother did not surrender on u for any things u did, Much less you? You're the reason with Ur sister she still striving. You won't help Ur mother by killing urself, Instead u will make all her efforts void, on drain. Plus, U still got Ur sister, Who's gonna take care of them when Ur gone in the future??? Imagine that. Bro, this is the slice of life. Sometimes Good sometimes Bad. I'm same age as u and have some bad life too, Started working as a teenager until now so I can provide for my family esp my sister. And many more problems etc, My life is on loophole how to provide, I can't even buy myself another pair of shoes. Sometimes I think of ending it also... But I don't fear death, I only fear what will happen after my death. Who's going to provide for them, who's their foundation if I'm gone. I cannot. Idk bro, I can't judge how the way you feel but please, Maybe soon life is on our side. There's always rainbow after rain, I'm still waiting for it. Hope it does.
