My nana died yesterday and I'm having to start thinking about her funeral, I'm having panic attacks. How do you kick 'family' out of the funeral without making a scene?

It's a very confusing situation krista, I have a 'sister' (she stole everything my nana had and tried to kill her twice thinking no one would notice) my nana had a restraining order against her and told me multiple tines she didn't want her at her funeral, she made me promise to get rid of her if she had the audacity to turn up, she's stupid and cheeky enough to come though as is 2 other 'family' members my nana didn't want there (another very long story).
