UK immigration

I am Libyan student and I have money difficulty to fund myself and my family here in the UK (due the situation in Libya my funding has stopped several months ago). I do not have enough money to renew my visa and to fund myself and my family. In addition, we are unable to go back to Libya due to civil war there and no schools, no health system no electricity for many hours during the day, killing and kidnaping everywhere.
Could you please help me and tell me what to do to stay here ( I been here now for seven years). Thanks.

Perhaps seven years child or asylum?
