I strongly suggest calming down and trying to solve this in a sophisticated manner. Threatening MTGOX will not help you get your money back. MTGOX has a daily/weekly transaction barrier, so you can't withdraw huge amounts at a time. You can however exchange your bitcoins in to EUR (That is your local currency, right?) and slowly send yourself the euro every week until you reach the full amount.

Also, it seems as if you bought €100k worth of bitcoins several months ago, those €100k are surely a lot more by now? Does not this make you happy, rather than sad? You have essentially increased your life savings by a huge amount!
