Help a victim of identity theft

I am a danish woman who just became a mom for the first time in august. It is the most amazing to be a mom and this should be the best time with no worries and only focus on your baby - but - I have been a victim of identity theft which has put me in depth of 300.000 dkk (and this is without interests), unfortunately I am left with this depth the creditors has no feelings and just want their money, even though I haven’t made The loans or used the money. I am on maternity leave from my masters degree and am on SU/state benefit the next 3 years which leaves me with no possibility of paying them off and the amount will just increase more over the years. I want to make a good future for my boy so I need instant help in this.
