How to extend my visa from Tier 4 category

Hi,

I am currently on student - tier 4 - visa and my visa is due to expire on 15 January 2015. I have completed masters in law from a reputed university in London but have been unable to secure a job offer. In the beginning of my academic year, I had an accident at a train station because of which I became disabled. It has been over a year and I am still recovering from the disability. I have also initiated a personal injury claim against British Railways. How can I extend my stay here in UK? Is there some visa category like HSMP or PSW available? or can my visa be extended on the basis of accident? what are all the possible options? I am an Indian girl.

Thanks in advance.

cheers!
