Dear Sister,
I don't know the reason why there are problems in your family, but God can fix the problems and do the need.
Be truthful and keep love with you, then you will get mercy from people as well as from God. Proverbs 3.
The above sentence is true and this helped most of the families, even in this site members too. You have to love others like God loved us. Be truthful. This will make way for better relationship with your people.
You can't expect to change everything in over night. It takes time to change.
If you please God, He will work for you.
Be blessed.
