Estranged Uni Student - best options?

Situation: I'm estranged from parents, in debt because I borrowed from a friend to cover the difference while Student Finance England was dragging their feet and my life was going sideways and I have absolutely no idea how to make sure I make the most of what I'm currently getting.

I've been put on maximum student finance rates + I am getting a bursary from the uni due to my situation. The debt itself I can handle - no interest, and I should be able to cover it with my next bursary payment and recover from overdraft in the next academic year. I'll be in uni for 3 more years, so I want to try to make the best of getting bursaries and stuff like that.

I just have no idea what to do next - I know that I'm technically meant to have an emergency fund, but rent is already about 70% of my income from SFE and the bursaries, so even a month worth of savings is way out of reach.
