Talking to family about newly diagnosed epilepsy

I'm 25 and have recently been diagnosed with focal aware seizures and secondary generalized seizures. I had my first grandmal seizure back in June, a week after telling my dad that I was thinking about talking to my doctor about getting checked for seizures (due to an increase in episodes of difficulty with speech and understanding speech/ metallic or rotting smells/ high frequency buzzing/jamais vu/ disorientation and memory lapse.) My neuro believes that I have been having these episodes since I was a child. My problem is that I have no idea how to talk or explain to my family about my epilepsy. I have had issues with anxiety, major depression and severe insomnia since I was a very young child (my neuro thinks this is partially due to my seizures) and i've never bothered discussing these seizure symptoms with my family prior; I thought it was just a normal experience because i've had it since early childhood and was told that it was due to my mental health. I'm not sure how to explain to my family after all these years that these little episodes aren't just a symptom of my mental health and that not all seizures look like tonic-clonics. Has anyone else had an experience even vaguely like this? It would be nice to know how others talked to family and friends after being diagnosed as an adult.
