I know what you mean lilly. And you are not alone. But I have learned and do well in separating myself from everything that is either out of my control or does not apply to me directly. We are only harming ourselves when we get involve with too many things. I told my mom, let my siblings be, let them do as they please, let them live, and let them make mistakes. Enough trying to covered for them, holding their hands, and spotting them. I feel guilty at times for not always being there for them, but I do what I have to for myself and my princess.
About two weeks ago, everyone was at mom's place. I say thank you to them for being understanding and that I will always be a call away when they truly need me. Other than that, if they don't kill anyone and has done nothing wrong against the law or humanity they should live their own lives and I do mine. Siblings and families will always be there no matter what, keep that in mind.
