Can laryngitis be psychosomatic?

Does anyone know whether laryngitis or a lost voice can be psychosomatic? My situation is rather strange. First, I've been smoking cigarettes and abusing my throat badly. Obviously, that could easily explain my condition. However, there is an extremely, EXTREMELY important telephone call that I need to make and which I have been putting off for approximately 10 days. There is a tremendous amount of anxiety and outright fear hovering over me in regards to this call. I've been having major panic episodes for over a week because of this, and in fact the reason I've been abusing myself is at least partly due to this. I do realize how utterly ridiculous this, considering the smoking, but I want to know what kind and how much damage can be done from anxiety/panic/PTSD. If worry and anxiety is intense enough can one actually cause an ulcer or otherwise rip apart ones gut with stomach acid or bile? This is probably the dumbest question I've ever asked in my life, but to what extant can the body murder itself? Can a person literally will their body to attack and kill itself? I should add that I've been coughing up blood off and on for a couple days. Tweet
