Hi Tiss,
Id's like to Bobby123 and welcome you to the site. Wow that's an emotionally distressing couple of days that you had . I'm sorry that you and your family are going through this.
I'm frustrated and incredibly hurt, because I let what she says get to me.
We're all human and it can be difficult at times to not let it get to us even people with thick skin have a problem with the words getting through. I suggest to read as much as you can about the disorder once that you understand why your D acts the ways that she does then you'll realize that it's not personal, you can also work on becoming indifferent with the behaviour you neither like it or hate it. Does she have any siblings?
