Don't take anything your dad has said to heart. It sounds like he has some dementia. Your mom and sister may have denigrated you to him. It does sound like your family's dynamics are quite toxic.

It also sounds like your husband is in the habit of putting you down. No one deserves to have their spouse talking to them the way he talks to you. He seems to see you as an easy target. You have every right to protest his disrespectful manner. If there is still love in this marriage, then maybe you could sit hubby down and tell him that calling you "crazy" is not okay. Arguing with hubby won't help. I would recommend that you learn how to give him the cold shoulder when he talks to you in an insulting way. Walk away from him when he gets that out of line. But tell him why. Then ignore him until he speaks decently to you.

Your husband is habituated to looking down on you. It's a bad habit that will be hard to break. But listening to those put-downs is damaging your soul. That family of yours got you used to being talked to like you were nothing. So hubby figured he could do the same to you. It's time you stopped being everyone's whipping-girl. Hold your head up and stop believing the stupid stuff you've been hearing from mom, sis and hubby. You are a precious human being. Tell yourself that everyday. Until you believe it, no one else will.
