Do I still have epilepsy?

Obviously I should talk to a doctor but I thought I’d check here for any similar experiences. I was diagnosed with epilepsy when I was 13, had seizures throughout high school, tried different medication but Keppra was the best option. The summer of 2010 I had a seizure(I was 20); I haven’t had one since. My primary care doctor a few years back suggested I’ve possibly outgrown my epilepsy but was hesitant to take me off my medicine so I still take keppra to this day. So, being 15 years seizure free, is it possible I don’t have epilepsy? Should I bother trying to get off the medicine? Or keep with what’s working? Would love to hear some similar experiences.
