Look. I've had parent issues recently, and let me give a tip. Parents never say what's on their mind. I thought my dad was just being an asshole by saying only straight A's would make him happy. But really, he had screwed up more than I had, and didn't want me to go through it, too. Chances are, it's something your grandparents did to them, or they feel that they did something wrong and don't want it to happen to you. Even if they say they hate you, they don't. They love you. Otherwise, they wouldn't keep you. They'd dump you out on the street. Take it from someone who's gone through it. If they refuse to listen, then that's them. If you have a problem with someone, talk to them. And if you can't find someone who can. Because even though us strangers can offer advice, we can't intervene with you and your parents. You need someone who can, honey.

Hope I helped. <3

Don't run away. It'll fuck your life up even worse than it needs to be.
If it's really that bad, see if you have another relative you can live with. I wouldn't recommend living with a friend, at least not for a long period of time.
It usually ruins the friendship, or at least from what I've seen when my friends lived with each other.
And you have to bounce from friend to friend, never having a definite home.
There's a chance you could just get picked up and get taken back home.
You'd be risking your friend's parents as getting taken in for keeping a runaway, too, if your parents actually call you in.

Try working things out with your parents before you go and fuck up; living on the streets is harder than you think it is.
At least now you have food, a roof over your head and a warm bed at night.
You run away, you don't get any of that.

Running away is not a good solution, it's much harder on your own than you think it is, especially for a teenager. I know you feel like they don't love you and you're not good enough but I'm sure that isn't the case. Your parents probably just feel that they are doing their best for you and don't realize how you feel. It is unreasonable to expect a child to be perfect but some parents just don't get it. Stick it out and keep trying to talk to your parents, you will be a lot better off in the long run.

Okay well...I just want to say don't run away...that's bad, and what if you get attacked by something! That was honestly always my fear, and I always have these dreams about running away and such...and I can 'run away' now if I want, because i'm 19 and old enough to move out on my own but...I'm going to school here, so I still live at home...yay!

But I kind of know where you're coming from...because my parents would get mad if I got a B+ too...and you always want to tell them...of course you COULD lie and say that you got an 'A' OR only tell them the grades where you got an 'A' or...well I really don't know. :(

But I feel your pain.

NEVER I repeat NEVER run way from your problems.
My parents land hard on me too whenever my grades slip, but then I know they only want me to excel so i won't have problems later on in life.. I'm sure your folks think that way too. As for them getting mad when you point out their mistakes, i'm sure they're thinking that you're back talking them and that you're not respecting them.
Everyone has problems. Next time, just tell them you'll do better and that you find it shameful that you got something other than an A.
Or just stick with the you'll do better next time. :D

Death is the last stage of life.
Why fear it?

You think running away will solve your problems?
You think that by packing up your stuff and going to live with a friend will rid of all your problems?
If you do, thats a sign showing how weak you are.
1. Running away is pathetic, if this bothers you that much, talk to them, see a counciler. Stand up for yourself.
2. If you go to a friend they'll
A. Kick you out
B. Send you back to your parents
C. Your parents will find you
D. Your friends parents will call your parents.
3. The police will obvioulsy get invovled.
4. How will you afford to eat? You can't just borrow off friends all the time, if you do, you won't have any left. How do you think homeless bums on the street got to be in the situation they are?
5. You could easily get raped, or make a stupid desicion like taking drugs.
6. If you run away from them, you couldn't go to school because they'd obviously send you home if they knew your parents didn't know where you were, so how would you earn an education? How will you go to college? How will you have a life?

I don't think you hate them at all. You just hate what they do. I think they want you to try your best. Running away is never the answer... and besides, things can become a lot worse with your family if you do. Once I thought running away was the answer and the next day I was put into a mental hospital because my parents thought I was unstable. Trust me, being hospitalized is never fun, but in the end you realize whats happened. Just don't do anything that part of you says not to. Even the slightist urge could make anybody make a wrong decidion.
StarBlazerM31 has a point too. You should listen to all the people who have posted here. It's good advice.

I'll give you some advice. I was exactly like that. I seriously cried every single day for a long time. My dad told me that he didn't love me and that he would choose anybody over his kids in a heartbeat. My mom spent all her attention, time and energy on my siblings who were so bad (who punched me so hard and hit my over the head with chairs) that she had no time to love me or give me anything. Even when I was so good. When I got good marks and everything she wouldn't give me anything. But it got better. I just stopped caring. I started to hang out with my friends more who really helped me be a more positive person, and spent less and less time with my parents. I know this is a hard thing to do though, depending the situation. But my friend also had a miserable life with her parents and recently she was "kicked out" because her brother stole from her and she accused him. So she moved out. And hasn't talked to them since, and they want her back to pay rent and smoke pot with them and stuff and my friend is like, "HELL NO!" and it makes me feel so good inside. I'm moving out soon too, but it has DEFINITELY gotten better. Much better. So things will improve!
