Hi Cali,
On another note...if you're depressed, discuss medication with your counsellor. That combined with therapy and alanon should help tremendously.
The eating issue is a moot point at this stage in your life. Things happen in order. The time is right for you to take care of yourself in regard to your mother's problem. It will come together. I see it with my son who is recovering. His eating has been out of control the year he's been sober. But he's in therapy and on meds. The rest will follow.
Take care and be well.
