How can a Mom Hate Her Own Daughter so Much??

I ask this question "how can a mom hate her own daughter?" to myself a lot lately. I know she loves me and wants what's best for me. Every parent wants what's best for their kids. I wonder if my moms mom (my grandma) hated her and treated her with disrespect when she was growing up.

I mean my mom judges me way too much and is so disrespectful to me. The other day she judged me on my hair and she was telling me that it was time for my haircut like excuse me it's my hair not yours. I miss having my long hair I love my long hair and I want it back. She told me no you don't need long hair anymore it doesn't look good on you and it just sits on your head. Like what the??? and I said you dare to have my hair cut I'm gonna have them shave your hair off. I'm not even kidding either I will. my hair is barely growing right now hell to the no I don't need another hair cut its my hair I can have it long or short. I told my friends about this and they both said what the heck??
I tell my mom when its time for me to get a hair cut and she takes me to get it done. She doesn't tell me when I need my hair cut. You should be able to tell your mom when its time for a haircut not the other way around. I'm like yeah I know right?

Than the other day she started getting so mad at me because I was wide awake at 5AM in the morning the other night and because of all the headaches I've been getting and my head injury I've suffered from she thought I wasn't getting enough sleep. Because I've had headaches almost every day and she's like telling me to go to sleep at 11PM and wake up at 8AM every day for 2 weeks. I argued with her for a good while and said uh huh sure whatever. I'm not going to bed at 11PM she got mad cause I should be getting 8 hours of sleep. So I faked it and said fine I would go to bed at 11PM so she'd get off my back. Well later that night I didn't go to bed at 11PM I was supposed to but Jennifer called me on Skype and talked to me for awhile till she went to bed. I really didn't go to bed till 2AM and no sign of headache and I slept really well the last few nights and I still gotten headaches no matter what. And of course my mom told my grandma about this like oh my gosh you have to tell grandma its not really her business of course she doesn't like that I say up late either. It's like she's controlling my life and its getting annoying. I'm the adult now I can do whatever I want she doesn't have say in what I do anymore and it seems like she wants to see me fail in life and she doesn't want me to succeed in life either a least that's what it feels like.

I'm not her 2 year old anymore.  I know it's sad that I'm growing up freaking heck I'm almost 21. They don't have guardianship over me. They dropped it when I turned 18. I'm glad they dropped it I already have problems with my parents anyways don't need them controlling my life.

Freaking heck its my life I'm not gonna change because she wants me too. She's trying to change me into someone that I'm not and for someone that she wants. Freaking heck I'm only once let me live it up and let me screw it up for once. I've been getting so mad at her lately we haven't gotten along at all  when I was growing up. I haven't really liked my mom at all. I think ever since the way she treated me growing up kind of scared me for life. I thought a mom was supposed to love her daughter
no mater what she does but I guess I'm wrong. I'm so happy me and her don't get along I couldn't save my life to get along with her. I think its meant to be that way. It's gotten worse growing up as a teenager there was no way getting along with her and id think as an adult now it would be a little better getting along with her but nope. I do respect my parents though I'm old enough I can a least give them some respect even if we don't get along I'm mature about it and show them some respect.

But if I ever have a daughter in the future I'm not ever gonna treat her this way. I'm gonna be the cool mom for my daughter and be a mom that she can get along with and be able to talk to me without no problem and I will know what she's going to be going through as I've gone through it all growing and changing. Hopefully my future daughter and I can be able to communicate with each other. I don't want my daughter to hate me.

If things were different than maybe my mom and I could get along but I have my reasons to hate my mom and be happy that I don't get along with her I know she's trying to care for me but she can stop. I just don't see us getting along anytime soon.
