Zhann - I'm so sorry to hear that you're having these problems :( 

I have a friend in Copenhagen who has ended up in a first-floor apartment which she hates.  She got together with a group of people (one guy started the group by advertising in the newspaper) and 4 or 5 of them are trying to buy a large house 20 minutes outside of Copenhagen, then hoping to break it up sensibly.  It has gardens, big outbuildings where they can run a gallery and studios etc..  If you can't afford to buy on your own would you consider buying with some other people?  Obviously the legal aspects and running costs have to be worked out thoroughly, but that's no different from buying an apartment and having to pay monthly charges.
