My best friend/crush and I were talking and the subject somehow went to talking about death and she said she had a feeling shes going to die in a car or plane crash, now I can't stop thinking about if I lost her. She travels alot and I'm fucking terrified of something happening to her. I feel like I can't breathe, I can't stop crying, I feel sick, I hate this and I don't know what to do about it, someone help?
