Hi, can I tell you about this from both sides?
I have three daughters, the youngest is seventeen, so I do know exactly how fraught these times can be!
From your side, you want to be treated like an adult, but you don't feel like one all the time! You ar busy finding your way in the world, who you are, and what you want to be, and it is very confusing, sometimes frightening. There are days when you hate yourself, and everyone around you, and your parents don't seem to understand, and they just nag and have a go all the time.
From their point of view, they know their 'little girl' is turning into a young woman, and it's difficult for them to make the adjustments. Your mood swings confuse them, your hostility frightens them, and they just want you to be safe and happy - I know it doesn;t feel like that, but having taken care of you from zerio to now, it's hard for them to let go and let you find out things for yourself, good as well as bad.
Yes they nag and moan, but that is only because they love you and want to keep you safe. It's easy at this time in your life to believe that the world is an exciting place - which it is, but its can be dangerous as well, and that is what your mum and dad look for, when you don;t always see it.
So yes, it is a phase, and it does last a while, but you will all get through it - honestly. My eldest daughter and my wife almost came to blows sometimes, but they are as close as sisters now - this fighting passes off, and everyone gets on again.
Man time, try and be patient, and look at their motives for what they do and say. It is rooted in loving you, and wanting to look after you, and yes it's a pain, but it beats being ignored and unloved!
