My mom thinks that the Bible is the only thing that can save you

I stayed up all night last night simply because I wasn't tired enough, and it got to the point where it was so late into the night, it was better if I just started the day. I cooked myself a breakfast sandwich and decided to go back to bed at around 11 AM and take a short nap, only to wake up at 2-3 PM to the sound of banging outside of my room. At first, I thought this was someone at the door who knocked too loudly until I heard my mom yelling at my brother for some ridiculous reason. It's not like I was phased by this in any way because it's unfortunately common for my mom to just yell out of nowhere and disrupt my peace, but I think I heard a little too much before I could drown everything out with my headphones. I don't know what my brother was upset about, but he threatened to kill himself in front of her and she decided to basically call him stupid by saying, "This is why people send their sons into the military, so they can make them strong and not act weak like you." And then she said that there's a devil inside of him making him think this way and that the Bible and God are the only things that can save him, because apparently, my mom doesn't give enough of a fuck to help him out herself. She has no idea how to comfort someone properly and this may be also why I'm terrible at doing the same, but at least I don't think a fucking book is going to help someone because that would risk someone turning into the exact shell of a person my mother is. Reading a book instead of actually dealing with your problems won't help, especially in this situation, and it wont make you a better person. The amount of times I've thought about killing myself is alarming, and I haven't done it still because I don't say shit to my mom, I know that letting her get involved with my problems would be a threat to my peace. It's rough having the one person who should be able to take care of me be insanely ignorant, and I get heartbroken every time I'm at my lowest because I know she can't help me, she's shown me well that she's not a good mother. I don't know any other reason to be hopeful other than my future, because some people tell me I'll be successful, and I'd do anything just to have the peace of waking up next to the love of my life. But I also look at the state of the world and wonder if this fighting is really worth it in case everything burns down and I never actually get the life I want, then again, I would rather die fighting just in case everything ends up just fine. The one thing I want more than anything is some sort of upper hand who I can trust, and have them tell me I don't have to worry, and I think having that is the greatest privilege of all time. One day it got so bad to the point I actually tried turning to God just to see if I would feel any different or any more hopeful, and I didn't. I didn't feel any magical presence in or around me, and if God cared about me this much I wouldn't want to kill myself right now, and the world wouldn't be so fucked up. I don't see the point in creating an imperfect society and making them submit to you, then saying if the people don't believe in you, they'll burn in hell. If that's the kind of God that exists, that is a cruel God. If there's anything that's going to save us, it wont be God either. The only thing we can do as the human race to improve is to love and care for each other, I'm tired of hearing that an imaginary man in the sky should be your closest friend when we scientifically need each other, everyone needs each other more than ever right now. Why can't we let people live?
