Help for a UK student with housing and money problems.

So July my mum is kicking me out and I still have a year left of A levels, how can I get a council flat?
Also I will not get any dole while doing my A levels. I’m looking for a job but it’s hard to find a part time one. Also I don’t get any sort of EMA as my parents make more than 21,000 even tough they are giving me money. What can I do?
