What she doesn't no

My mom is one of the best people in my life
And I thought that i could trust her with everything
I have never kept a serious lie from her
But I guess she doesn't care how I feel
She told me that she had quit smoking a while ago
and The bad part is I believed her cause I thought she would never lie to me
But I was sooooooo wrong and I feel so hurt inside
I was looking for a piece of paper one day when I found a pack of cigarettes in her purse
I thought to myself no no she must be holding them for someone
Then a week later the house started smelling like smoke
I was starting to get scared
Then I found more packs all over the house and they were all hidden
Then I find an ash tray in the kitchen where she has been smoking
I thought that I could trust her with everything but I guess i was wrong
She lied to me for all these years. And now she is trying to keep it from me!!!!!!! And the worst part is, she thinks that i don't no. But what she doesn't no is that I am slowly dying inside and it is all her fault.
