I'm posting this on behalf of my sister. I'm starting to be worried.
My sister and I share everything. She is an exceptionally bright 13-year old, and I am 18. She cries a lot, almost randomly. She eventually told me that she can't spend a second not thinking about anything, because when she does it, she gets a terrible fear of death. Her heart rate goes up, she cries, and it's interfereing with her life. I wanted to know if anyone knew of any resources I could use to help her with this. It's really starting to worry me.
