We are all on your side vampirequeen and any angry comments that I have made are aimed at your dreadful sister and (sorry) equally dreadful Mother. You have made a huge success of your life despite these people, you have had a good education, have raised a lovely family and are much loved by your DH and lovely new family. Your DH and his children and your daughters see a loving wife and Mother, and they choose to spend time with you, they want to be with you, so are you saying that they are wrong to love you? Just send a text don't go to lunch, why not take your DH out to lunch instead? Just the two of you?
He is the one who deserves your time and attention and wants to be with you. You have been very brave describing the horrors you have experienced, and very eloquent in your description of your mental health issues, so much so that you have made many other people open up on here about the misery they have suffered from their Mothers. You have helped us all, now start to help yourself.
