My sister is violent to herself, talks to people who aren’t there, and the person she was staying with doesn’t want to help her anymore; where do I go from here? I’m estranged from my 50yo son; would you recommend I write him a letter asking him to share his grievances with me? My sister and her husband refused to meet with me 2yrs ago about problems in our family; should I write her a letter and give a copy to my family? I just found out the man I was in a 7yr relationship with is addicted to crack. Should I let go or try to help him?
