My mother in law intereferes o lot in me and my husband's personal life... it is to extremes now... dont know what to do... please somebody help me? I need some mental support... am lost completely

What form does this interference take? What is your husband's attitude to it? How involved is she in your lives? Do you have children that are her grandchildren?

Since I am only going off what you have written. I need to know more. What exactly is she doing (interferes in big or small situations). How does your husband feel about it. What does he do about it. Are you and the in law close? Have you said anything to her about how you feel?

That's something you, and your husband, have to talk about, and find a strategy that you both agree on, that makes you both happy about.
