FE Student Help!

I left school at 16, worked for three years, really enjoyed it and then the company closed so i was made redundant. Had a bit of a hard time, but then found a new job. After realising i didn't enjoy this job, and wanted a new line of work, i decided to go back to college and i love it! However, will higher education students, you can get loans etc.
I am looking for a job, however in the mean time is anyone aware of any benefits i can get? I'm expected to live off of £20 a week (adult learning grant) which i cant touch because i've gone so overdrawn.
I don't understand how the government can throw money at jobseekers, however when i'm going to college to better my skills to get a better job, i get £20! I too have bills to pay and a car to run! I'm not entitled to a student bank account i don't think as i am not studying a higher education course so am paying stupid amounts of interest on m overdraft, which is just getting more and more!
Anyone know anything i'm entitled to? I'm desperate!
