Mei Mei,
So glad your mood is improved and you seem to be coping better and accepting life as it is. Certain people family members in particular often remember how we were compared to how we are now, and for the life of me they just can't cope with who we are now. For now you seem to be coping with the changes that you have had to live with on a daily basis.
Not everybody is comfortable dealing with change as we here on the forum are. Face it nobody likes change! Even we find sudden change difficult to deal with. Talking about it is one thing. Group work is another, separate therapy with individuals is another.
There seem to be so many issues with you and the way you relate to your family, have you tried leaving notes around the house? Opening up a dialogue with certain family members may be easy or hard to do after so much time but it has to start somewhere. In the past, I have observed a family who I thought were close to each other but when their matriarch died tragically in a fire they all reacted differently. Each of the 3 children have their own way of reacting to grief.
My best friend has acted as the anchor to the family thankfully, and has been supported by his good friends. Each of his two elder sisters at first reacted strangely the eldest wanting nothing to do with my lifelong friend (we have been friends now for 43 years) for some time after the matriarch's death, the 3 children could hardly speak to each other, now my friend is once more speaking to the younger of his sister's.
There unfortunately is nothing you can do at this point but wait and be patient and if you believe in God, pray. Perhaps, when you are out in the park walking your dog, you may chance upon them or even suggest it yourself. Parks are big open spaces where you can walk away from a conversation when you find it uncomfortable. I remind you you can't do that (as easily) in somebody's home.
Take care glad you are feeling better!
Mike
