University is it worth me going?

I want to go to university but i don;t have enough, i feel angry in my self as i don;t have enough qualifications to go to university and have worked my *** off the last four years. Should just quit and get a shitty job, or my dream of a degree. im starting a two year btec national diploma . But in my mind by finishing that course i would have taken 6 years to get to university and most people take only two. I have serve learning difficulties and dyslexia but feel disappointed what should i do, any tips or advice would be much appreciated.
