>>1 it may be difficult but you need to let them be, unless of course it gets to a potentially lethal situation in which case you should call the police. Parents make their own decisions and have their own problems and as children, we can't always make things better for them, sometimes we just need to let them figure it out for themselves. It can really stress you out if you're always trying to get them to resolve their issues, you should really focus on yourself. It may sound selfish but honestly, it really isn't worth all the stress getting involved with them. I hope this helps, and good luck, keep us posted ^^
