Wow, Nolus. That was very appalling and heartbreaking to read. I'm sorry that you're going through so much right now, it sounds simply awful. It seems to me that your mother truly lacks the ability to feel any sort of empathy. She seems oblivious and indifferent to the stress and emotional turmoil you are experiencing (not only at home, but at school as well), and instead of listening to you and trying to find a way to resolve some of the problems that are plaguing both you and your family, she seems more interested in asserting some sort of "point" that she feels you are apparently overlooking. When you tell her you feel like she doesn't love you, instead of trying to get to the root of the problem, she gets defensive and shifts the blame to you. She is even nonchalant at the idea of you committing suicide. Her approach to parenting is highly dysfunctional, to say the least, and she very likely has larger mental and emotional issues that probably should be examined by a professional in a therapy setting.
But sadly, if she's not willing to seek help in dealing with her problems and the problems of your household, or even talk to you about it in a open, non-confrontational manner, then you need to distance yourself from her emotionally and start realistically planning to get out of her household. I know that is an idea that might seem overwhelming right now, and it's true that it might take a longer stretch of time than you would like to ultimately accomplish, but if she won't change, then removing yourself from her sphere of influence is only route to go in the long run. As someone who also grew up in a very abusive household, I can tell you that leaving was both the best therapy, and the best solution when it came to resolving my own inner conflicts. My life completely turned around for the better. And this is why you should not feel tempted toward suicide, Nolus - because you don't know how good life can be when you're free from the abuse. The pain doesn't have to follow you around like a ball and chain for the rest of your life. You can have a fresh start and live a good life. You just can't give up hope.
Until then, looks for ways to physically and emotionally remove yourself from her dysfunction. I agree with 1PceXperience - spend whatever time you can out of the apartment. Go to the library, go to a museum, go to a coffee shop - make whatever free time you have between home and school your reprieve. Turn to music, to literature, to art to soothe yourself when things get rough. Work on disciplining yourself to not be baited with your mother's emotional and psychological abuse, because her opinion doesn't validate you, Nolus. It doesn't shape your existence. See her dialogue for what it is - the venomous mutterings of a cruel and unbalanced woman. Because you are very well-liked and highly thought-of here, you know. You have lots of wonderful qualities that we can see; your intelligence, your good looks, your creativity, your sense of humor, your warm and friendly nature – I could go on! You have a lot to offer and a lot to live for.
Don't give up on your life, hun. Things can, and will, get better. It might take some time and effort, but few good things in life come easily. You are strong and you will get through this hardship, and be better for it.
And you know you can always talk to us here. :)
