Also I've been thinking serious thoughts. About my biological mother. I though why did she fight for me when I was being adopted by my grandparents. I want to know why? I mean I thought what if there is something wrong with me that only she knows? Or that she only wanted me to watch any other siblings I get... I care for her to,.. But.... I don't know anymore.

your thoughts are way to conflicted. in one paragraph, you hate her, want to be her friend, and are concerned for her. before you do anything, you need to get your priorities strait.do you want to be her friend, or do you not?

I understand how you feel. I've had friends like that. Maybe what you need to think about is why is she like that? You say she has older sibblings, maybe it's a cry for attention. She could be very easily shoved to the back burner at home so at school she does what she can to get people to notice her. Perhaps why she complains all the time about other things is because a lot of blame could be placed on her, like things that happen around the house. Complaining and placing the blame on others could be a way of dealing with that, making her not feel so alone. Like nit everything is her fault. Also If she's been picked on a lot it could be why she's so defence over little things. I use to be like that. If someone touched my stuff or gave me a compliment I felt as if they were making a joke of me and instead of being thankful or understanding I gotean and defensive. You said you thought she was cool to start and you'd still like to be her friend if it wasn't for how she acted now. that girl is still in there! You just need to find her again and stay with her. When she goes on a rampage stand up for her, when people try to blame her for stuff take the blame off her, if she's gone over board tell her in privet nicely. Sometimes all people need is one person to sand by them no matter what.

Ok thanks

she is a insucure person , it is normal she act ragging about litlle pathetic things , but thta doesn t matter to much , you just have to decide if you want to try and be friends or just doesn t give a crap to what she does

Well I understand what you are saying, I mean happened to me a lot in the past. I tolerated the annoyance until it stops, but in the end I blew up and had enough. What I'm saying is that you did the right thing not starting a fight, but you need to release the steam somehow, or else you might end up hurting your real friends. I experienced being isolated by my own friends because of the same thing. It's a friendly advice i'm giving.

I had the same problem. I snapped and punched the kid. Problem solved.

... Yes, Don't resort to violence, honestly that would only make the situation many times worse.
I understand your situation. At this point in time, I have someone close to me who is very much like that.
No, you're not bad to hate her, however, hate is really a very strong word to use here... you sound like maybe you're more frustrated with her then anything else. My suggestion, when things start to get bad with her... take a step back, take a deep breath, and then try to talk to her about it.
When you have to move her stuff, maybe just tell her, "I'ma move your stuff cause it's in my way, kay?" Then she won't really have a reason to get upset.
If it gets bad enough, you should let a teacher or the principal know whats going on. I'm not sure where you are, but most times, those people can help you out.

And with your issues concerning your mother... Everyone has problems with their parents from time to time. Best solution there, take the time to try to sit down and talk to her about your concerns. I know some people aren't this easy to deal with, but you'll never know unless you try!

Thanks guys. This makes me feel much better. I'll do y best.
