>My youngest sister has bipolar disorder and is supposed to get married soon. She’s alienated the rest of our siblings with her “emergencies,” demands, and accusations. Sis wants me to stand up with her, and I will because I promised, but I’m not convinced this is a good move.  How can I be supportive about something I don’t think is a good idea?  And what do I do if she wants me to run interference for her with the rest of the family?
