student loads or financial support for sixth form

I'll start with the fact this year were suppose to be my last year at sixth form so my A2s, but in middle of the year something happened which mean that i couldn't stay in school. The school allowed me to leave in the middle of the year and come back and finish my A2s next year. So after i've left i've move out and went to work, and because of a difficult situation i might not be able to move back home when i come back. So i was wondering if its possible for me to get a student loads, or some form of finacial support from somewhere while i finish my A2. or is my only other option is to work more hours? i've work part time at a restaurant anyway but i've only got 70 pound tops, which wouldn't be enough for travel food or rent,

any advice or help would greatly appreciated ....
