@brit- Perhaps she's in a lot of pain and does not want to talk? I know that when I'm in pain, depressed or not feeling well I don't want to explain what's going on and I don't even want to talk much to my husband. I want to be mostly left alone. My sister always calls way too much and when this happens I have my husband talk to her. I wont get on the phone. I know that you are a caring person, it's very obvious, but it may be that you are overwhelming her with your love and worry? Can you text her? Perhaps just send a friendly text- miss you, hope that you are feeling better, or send her a joke or a picture that she might like. To tell you the truth I love my sister, and my husband, but I hate to feel smothered. It reminds me that I'm not well and exacerbates my PTSD. Does this make sense?
