I'm sorry to hear about your cousin Regan. That's hard for you and for his family. You did all you can witnessing. It's in the Lords hands now. I'm sure they would love it if you spent some time with them. Unless they are dysfunctional and abusive. Then maybe just take them out to dinner, what ever you can afford, for like an hour, or half hour, what ever you can afford. one thing about grieving, when they are grieving and going through loss just listen. Most people just want someone to share the grief. Then talk about where he went and life after death.
