We're USEd to be close..

My mum is starting to annoyed me.hahh..
We're getting apart every second..whether in the same room, i just can't get along with her..Actually I hate that, so I did try and to talk something out.. f.y.i. it takes all my guts just to say/ask something...
But ALWAYS my line been cut short by her...or no replys at all. I dont like repeating it..if I do, it might get into a worst arguement right??
So I keep silent ..
Why,why?
Am I TOO small to be heard??
