My best friend is severely ill with a mystery diagnosis and she just got admitted to the hospital today. After 3 weeks of neurological symptoms and 2 ER visits. I’ve know her since I was 2. She’s practically my sister and for all I know, she could be dying. Her symptoms are certainly severe enough. She also tends to be overly-dramatic (also really emotional is another one of her symptoms) so was writing deathbed notes and crying. Last night was the first time I ever actually considered suicide. Since this has happened, my depression has gotten worse too. How do I deal with this situation?
