Dear Monica;
My Dear sister, one question, one step, one load at a time, and everything will be manageable.
People are at different level of obedience and disobedience.
some people rely on the saying that whom ever dies and in his heart a tiny spic of right believe in Allah, he will be under the well of Allah he may torture him or he may forgive all or some of his sins but he will end up in paradise.
Now the smart person will not put himself in danger, and rely because there are no grantees that he or she will be forgiven and hellfire is a sever punishment that should not be taken lightly.
We are on this earth to earn our place and level of punishments or enjoyment.. We certainly wish that all Muslims follow Allah's orders, but we cannot make them. Try your best with your immediate family like your husband and children, and remind the people you know and who are welling to listen, without being offended.. but avoid making anyone feels that you are telling them, or that you know best, or you are pushing them to go your way.
Be a good example and insha2Allah that will open there eyes.
Remember we are all fighting the devil and his army who is doing his job by keeping so many people busy in a worldly matters.
Do what you can, but do not take the responsibility of guiding all the people around you, otherwise you will suffer disappointments, and sometime isolation.
Enjoy what you learned, and keep on learning, and spread it to your family and mention it at the right opportunity, and May Allah guide the people to the right path.
Best salam.
