The best person to advise about driving with a medical condition is your local GP. If they believe you are fit to drive then you could apply for a new licence.

If you are applying for a driving licence for a lorry, minibus or bus (D2 form), there is a separate D4 medical examination form, which has to be completed by a doctor.

However, if you are just applying for a standard car licence then it is the D1 form and you complete a section on that form about your medical condition. The DVLA may then send you a medical questionnaire to complete and contact your doctor.

Please note that you can renew your medical driving licence online if you have diabetes, but it sounds like you have surrendered your licence so I believe you will need to do a paper application.
