Step-mother with Bipolar Disorder

Emily

I just moved in with my father and my soon to be step-mother. She has told me she is Bipolar and I really want to know all I can do to make it easy on her.

Now just so you know she doesn't take pills, she smokes cannabis which is legal where we are. Do not shame her for she does it for her own personal reasons and I will tell you off if you do say something about it. She is still functional and still takes care of my half siblings. She cooks, cleans, and is still a mother.

Other than that is there any tips I can get to help her out without stressing her or anything? I know very little about it so anything at all helps
