UK, Ireland / Help with claiming income support for a 16 year old who has left home [3]

I hold a polish passport but have been here 10 years. I am now 16. I have left home because of domestic violence. I need to claim income support but have been refused because I did not satisfy the habitual residency test. I have my passport but nothing else because my parents will not give me the home office papers I need. Please any advice appreciated
