Sorry to hear that....When I do long and/or multiple posts, I usually draft it first on Word or WordPerfect and then cut and paste it to the post. That way I have a copy of my trip reports to keep, and I don't lose my work. Hope you can salvage your report.
I typed it first in Word, but I'm the type that every time I read my work, I change it. So, I was able to recover most of it, and then make some different changes.
