Have you gone to counselling because I think she really needs it. The way I see it, she is either just being a teen which is normal or she is going through something and she is taking it out on you. I suggest counselling or just talk to her about it. Make her understand that you are hurting and listen also to what she has to say. I've read in an article that suggested that there is a possibility of an underlying disorders when your teen gets out of hand so contact professionals as well in order to rule it out with your teen's change in behavior. Either way, just be there for your teen and continue to help her with her behavior changes.

you are not alone. not understanding why today the teen can behaviour likve that. As a parent particular a signle parents, you work hard, try all your best. but end up, your kid hates you. this is must heart broken. I don't know why we should stay in this circumstance? I been try all the methods, there are nothing we can do. I believe they are selfish, until one day, they lose it, then they will feel what they been missing out. but too later, time pass cannot turn back.
