Is it normal that i dont care about anything anymore

ever since i was a little girl, my mom never really cared about me. she hasent worked a day in her life. she doesnt go to any school events i ever had. if i got a report card shed just say set it down and not look at it, if it was mothers day and i was so excited because i made her a gift, shed say oh thats nice and not even look at it, or when i got a really high mark shed be like thats good in the most monotone voice there is. but when i mess up like i forgot to clean my room or i acidently broke a glass or i was late for school (even though i was in elementary school and shes the one whos supposed to be sending me) she wouldn't make me forget how much of a failure i am and how id be nothing in life. she also used to call me fat pretty much more than twice everyday even though now i know i wasnt fat, i tried so hard to please her growing up but she never noticed the good things just the bad. my mom is really vain and selfish and dosent really care she only cares about that stuff because she thinks it shames her. she wants to look like the best mom their is even though she is not. she used to beat my big sister and she would deny doing so. and if she wants you to believe something you have to. shed complain about her problems and make ecuses on why she cant fix them even though the answers really simple. like shed say its your dads fault for not paying child support this month or you could get a job? its their fault they never offered to teach me how to drive when she could just ask.

now that im a teenager i just dont care anymore about anything. i feel like i have no motivation or no benefit out of doing anything. for school sometimes ill go to school in dirty clothes and worn out shoes, sometimes i wont even brush my hair or clean my room. i just dont care what others think anymore. Im really lazy too i just go straight to my room and lay down on my bed. im not saying i do that all the time because sometimes i do put myself together but i dont see the point. people would say im a pretty girl, im always worried about how much i weight and i shower regularly. but when it comes to everything else i just cant seem to care. if i cared about thoses things id probably be doing better. i never used to care about school and im trying a little now but not as hard as i could. i skip alot because my mom wont check my report card anyways, she doesnt go to interviews and she doesnt answer the phone.

I know i shouldnt stop doing good things because its for me not her but i cant seem to and i dont understand why im like this. i say i will change because im not gonna let her define me but i find myself procastnating. even when she gets mad at me emotionally abusing me everyday for hours because of this stuff i just dont care. i hate my mom and what she says doesnt bother me. i mean it still hurts but i dont care about her opinion anymore. is it normal to not care like this?
