why was my blog post deleted

I typed like an entire essay and I tried posting it and it literally evaporated, i clicked view entry and it was a 404. if someone could tell me why that would be wonderful 
(i'm dying inside) 

edit:
according to a reddit post this isn't just a me thing, and there seems to be no clear answer

edit again: yawns, I'll retype it at some point, but for now I might pick another essay topic and keep in mind to save it on a doc.
