My iTunes Library cleared out after the forced shutdown, how to recover it?

Question

So here is the thing, yesterday as usual, i was adding songs to my 10,000 tracks library's super organized as i do most of the time. Then i decided to shut down the computer  instead of just putting in of just hibernating him as i always do.. So my habit was to just close the laptop, this time i had it clicked to shut down but then i closed it before it really turned off. That means today when i opened it back it still was asking me if i really wanted to force quit the applications i had still opened, i said 'yes' and then the computer truly shut down. Then i restarted it again, opened browser, and when i open iTunes ALL my library was simply gone!
I know that i didnt trashed any of the .itl or .xml files the day before so i really shocked when i saw it I dont know why did it happened, i wasnt updating iTunes or anything else..
I went to 'iTunes' Folder in 'Music' folder, and there were the 'iTunes Library' .itl and a 'iTunes Library (2)' files along with the usual Extra, Genius .itl files and the .xml too.
So ive searched on the thrash that by casualty still had files from TEMP folder i had erased a few weeks ago, and there only Extra and Genius .itl files but no iTunes Library .itl file... So it was not a thing happened by my manual deleting.
I've tried re-installing the latest version of iTunes i found on the site (it was just a 'repair' since the version was up to date) and opened it again and there was still nothing :/
I checked 'Previous iTunes Libraries' folder and f****! The newest file was from March this year (2012), i knew that ive added hundreds of new songs since that date and one other thing, i knew that date was not the latest update ive done to iTunes, the last one was for sure way after that kinda something in May or June so i dont know too why did it not appeared that .itl file.
So i tried opening that 'iTunes Library (2)', and from my 10k songs it would only show ~8900 and then i tried the 'iTunes Library' from March and it would only show 9000 songs, So i guess im ****** up by 1000 songs difference... That is a lot a still, since they were all organized by Name, Artist, Album, Genre, Year, Rate, Times Played, Artwork,etc..
So now i have serious problems..
Do you have any suggestion on ways i could follow in order to find my 'Yesterday' Library infos and songs? With all the stuff it had? Like rewinding in time?
Even if you dont, and presuming i would want to add those 1000 missing files from the iTunes Music folder where, dont know why, says i have 14k songs, which is very strange since i always delete to recicle bin all the songs i want to clear out from the Library so they wont stay in folder and not in iTunes, so how could i add those missing 1000 without adding those other 9000 that would be repeated??
Please, somebody help me with this, because at this moment im really out of solutions and my Library and its organization are "my babies" and it would be a devastating loss to me if i have to ruined this way :S

Reinstalling iTunes won't ever repair damaged libraries or find lost files.
Unlike nearly all Windows software double-clicking an iTunes Library file does not necessarily open the selected database. Rather, iTunes opens the last database it successfully opened, or if that was in the "normal" <User's Music>\iTunes location, but is missing, it will create a new empty library.
You can open an alternate library file, or create a new one, by holding down shift as you start iTunes. Although you can open the library files in the Previous iTunes Libraries folder this way, your library will perform better if you restore the archived library database to the main iTunes folder in the way that I have described.
Your most recent library may be present in the main iTunes folder as a .tmp file, or recoverable via a file undelete tool, however either of these files, if found, may be partially corrupt getting you no further forward.
The two most recent releases of iTunes were June 11th and March 28th 2012..
Yes I read your post, but I don't know if you know all of the above. If you had a full backup of your library you could just restore that. It is possible that what you've tried so far hasn't yet brought back the most complete version of your library that is available to you. As a last resort you will have to work with what you have and add in whatever media is not in that version of your library, accepting the loss of recently added ratings, playlists & play counts.
You can simply add the entire iTunes Media folder using File > Add Folder to Library folder which should ignore everything already in the library and only add new (to that database) stuff. If there is any chance that your iTunes media folder contains .m3u playlist files the import process will also import all of those, which may not be what you want. iTunes Folder Watch would then present a better approach.
