My sibling is to stay with me whilst they 'reset' their lives. Happy to the extent that I can accommodate them and help sort out their finances/debts and general support after them having had a couple of dreadful years. What I need help with us setting boundaries about what is acceptable behaviour while living under the same roof. For example They drink, I suffer anxiety around drunk people, I don't want a tip- toing hangover existence , they have stayed before and been lazy and not helping in the running of the house. I don't want to be a control freak but I want us to tick along together without me being in a worried bossy " mother" type role. I want us to live without me being constantly worried about where they are, what they are doing, who are they with, How can I ensure that I don't turn into a nightmare control freak with a rule book. I'm 56 they are 42 . Any suggestions ?
