EDIT: I've reviewed the Reddit thread linked in another comment! (The Co2 guy)[1] Given that the original Reddit report was written as cogently as you've been writing I would suggest taking similar and related steps. I don't have anything more specific to add. Get things back to normal. Also you report physical illness, so this would go hand-in-hand with some similar reason. (For example, Co2 guy had severe headaches, that he didn't mention but which were a symptom.)
I've deleted the earlier version of this comment (in which I asked you to speculate on a motive for the email) as I think that it is more important to address the things that could cause these thoughts. It would be different if you didn't feel sick or weren't taking a high drug level.
I see a lot of similarities, especially because you mention physical illness (although the OP there didn't mention his headaches until prompted.) Try to solve them, as they're quite serious. Bear in mind that your judgment may be impaired at the moment, and that your family are concerned. Try to solve the external source of the issues if at all possible.
