Will I get no support?

I got a degree a few years ago, studied for 3 years, however since then I have become disabled, now I fancy doing a graduate diploma, part time cost £2780 a year.

I'm around 30 years old. My monthly income is around £350 a month. I don't get any benefits yet I'm too sick to work much more in my current job. I'm completely stuck in life. Hoping the diploma would open up office jobs to me, instead of the manual jobs open to me now.

Is there any help available to me?

Thanks.
