Yes get it . I have had flue and it took months to fully recover from . The only time I have felt iller was las christmas when I had septic tonsillitis and was (obviously now) suffering from undiagnosed diabetes I had had tonsillitis for 6 weeks before it went really bad and the it took 3 weeks of double strenth antibiotics to flatten it but was still not right for several weeks after that. I wonder what high bgs would do to the flu on second thoughts I dont want to know
Being Diabetic puts you in the "at risk" group for flu, you should get a letter from your doctors giving you an appointment for your jab at one of their flu clinics, at least thats how it works here in Wales.
I've had flu jabs every year for the last twenty years or so. Originally because I worked in the Theatre and it was cheaper to vaccinate the cast and crew rather than have flu go through the company, mutate, and go round again. Later, because I'm kinda asthmatic. Didn't get the jab last year and boy, was I ill !!! If they didn't offer it privately (Wales. - What can I say? We are the chosen people. ) I'd pay for it.
