I was diagnosed at 18 and the cause was unknown until I started retracing my steps. I realised I began having seizures after I started having problems in my relationship. My neurologist said that my brain tried to re-wire itself as a coping mechanism to help deal with a messy end of a relationship.
Gradually since I've been to university and had the stress of coursework and things, my seizures have progressed to tonic-clonic. I wake up not knowing where I am, limbs are numb and I speak like a baby. I am practically inanimate for the next 3 days. It has worsened since then and some seizures come seemingly unprovoked. The most annoying thing about mine is my memory loss. But I am quite content with having epilepsy, I've embraced it as a part of me and yeah, seizures aren't great but it makes me unique and I like that. If it's a part of me for the rest of my life then so be it.
