Do I have a problem?

I grew up around my mother always drinking she was never a bad parent but once we started losing family members close to us her habits got worse. I was always the child that had to tell her enough is enough and always there to listen to her. But now that I'm an adult I'm scared that I will turn into the person she was. When I drink I don't stop until I feel the effects. I get depressed and down but in the end all I want is sleep. I don't drink often because I am aware of the effects but when I do I just don't want the feeling to end. I think I have a problem.
