Hi Merol93,
don't worry you're not alone with the "bulk" removal of links from Google. This happen to every site like yours and unfortunately for you, you can't do anything to prevent this.
But consider that many sites "fix" temporarily this problem by changing the link of the removed post and by set the 301 redirect from the old to the new. There is also some sites that "fix" this problem by changing the domain name after some months.
Hope to help,
