She was an addict who died due to complications caused by her addiction. We were estranged at the time of her death because I couldn't cope with the way she had been choosing to live. My other parent died a few years ago, also as a result of addiction. I have siblings who were more accepting of our mother's choices. I saw her when she was semi-conscious and have no idea if she knew I was there or not. I don't know how I should be feeling.
