Mother's on percocets

My mother has 3 children, me age 18, my sister age 14, and my brother is 10. I don't know where she went wrong with managing her pills. One day she was fine, happy, and a good mother. The next day we were homeless begging family members if we could stay with them.

My mother was always a good mom. Always put us before herself. But, now her whole entire life revolves around percocets. When she does not have this damn drug in her she will sleep for days upon days. If someone were to wake her up all hell would break loose. And of course no one really knows what is wrong her besides me and my little sister.

A 14 year old girl should not be worrying about if her mother is going to wake up today or if the house is going to remain the way it has been for the past week.

A 14 year old girl should be worrying about her friends and going to the mall. When my mother is on percs it's like she is completely "normal" but she is actually like a robot.

She is up and cleaning, cooking, doing what ever she has to do but when she speaks to you its very monotone like a robot. Every week or so we get into fights about these pills but she always denies taking them.

I heard a person can only be helped if they help themselves, why doesn't she want to help herself?

If she sees her children crying, starving and begging her to stop, why doesn't she?

I just don't understand.

If she would just come out and admit it to everyone that she has a problem I will devote my life in helping her become clean. But until then all I can do is stand by and watch her whither away and be the mother figure that she once was...
