<human>: I have been estranged from my mother for a number of years, to vary degrees as she faded in and out of our lives. She had a long history of depression and other conditions and misuse of drugs normally used to treat those conditions. She overdosed and died last night/early this morning.

I feel that I'm still in a sense of surrealism and denial. Because of this, the hardest things I'm dealing with are logistics. I don't know how to tell her sisters, whom I haven't seen or spoken with in years, perhaps even a decade. I feel like they deserve all of the details, but I feel like I don't want to be the one fielding all kinds of questions and angry messages lashing out. I don't want to work out logistics of her cremation and whether or not she should have or would have wanted a funeral, memorial service, or anything. I feel lost in what should be the minutia. I feel like thinking about these things is blocking me from grieving/coping properly.

I'm sorry if this post doesn't fall into what this sub is meant for. I want advice, but I also feel like I just needed a place to vent.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My mom overdosed and died last night. How do I deal with the logistics of telling other estranged family and the postmortem process?
