confused and worried

Earlier this year I had LLETZ treatment and was diagnosed with CIN2, i went back for a follow up 6 months later and it has come back bad again, not sure what to think

or what to do, why has it come back so quickly?

Everyone is different but I too have had mine come back after laser surgery and a cone biopsy surgery. Keep going back for your regular colposcopies and good are very lucky, as I to have caught it before a cancer result. :)
