Hi there,
With regards to your employment, you should approach your employer about reducing your hours.
Have a look on here
http://moneytolearn.direct.gov.uk/ for possible financial support. The government currently offer many incentives for people going back into education.
May I ask what course you are studying? Most colleges offer advice and help with funding.
Good luck with your studies. I am a mature student, although I have had to finance my studies, I am really enjoying it.
