How do I withdraw

I am planning on withdrawing from uni at the end of year 2. Would I still be eligible for another 2 yrs of funding if I decided to go back in the future? Also can I use my previous study to go into year 2 at a different Uni for example 5 yrs in the future? Is there an expiry date on the funding or will i be able to use those 2yes at any point for the rest of my life? I would like to get a degree so I want to make sure im not chucking my life away but also mentally and physically i have proven I am not ready for Uni over these last 2 yrs but want to be able to go back when I am ready if possible. Can anyone explain how it all works?
