To me it sounds like hormonal changes. That was what started it for me, along with added stress. My suggeastion is keep a journal of things that happen, times of day and what was happennig. Even keep track of foods you ate, they can trigger it.

I suggest this, as for me things that did not trigger it now does. As in mid forty's things start shifting in our body's

Good luck and just remember if it is the epilepsy you got much support here!!
Though for you I hope it is only stress.
Peace and healing.
