Hi OP
I have you're type of epilepsy, I had it in it's other form (loss of consciousness full body seizures) as a young child then it went and came back when I was a teenager as the 'absence' seizures. The good news is, if you can get it under control with medication you won't have seizures at all, and can lead a perfectly normal life, completely unaffected by it. It may also come and go throughout your life.
The absence seizures are truly horrible, in my case, it's like your brain is overidden for a couple of minutes at a time and makes you think of the worst possible things you can imagine, nobody can really understand because you look perfectly normal all the while you're mind is racing, and your body is doing all sorts.
I learned to 'control' mine to a certain degree, it sounds really weird but I found it helped me to have a bit of a mantra, whenever the deja vu feeling would start just before the worst part of the seizure, I'd clear my mind and start slowly saying to myself (not out loud) shut up, shut up, shut up, over and over, and I found if I closed my eyes and pinched the bridge of my nose, it seemed to focus my mind and stopped the horrendous thoughts until it was over. It didn't stop the seizures but it helped me cope with the out of control feeling.
You may find that the medication they have put you on is not the one that works the best for you. I'm on tegretol slow release 800mg per day, which has always worked brilliantly, controls it perfectly. But when I was pregnant with my DD a couple of years ago, my epilepsy spiraled completely out of control, worse then it had ever been, as the pregnancy progressed so did the epilepsy and I was having 40-50 absence seizures a day, even on double my usual dosage. 3 times, for about 24 hours I developed epilepsy psychosis to the point I couldn't be with other people as it was like a panic attacks that wouldn't stop and paranoia that was off the charts, I couldn't even look at the dogs because I felt they were trying to communicate with me, it was the closest I'd been to madness, and it gave me a new found respect for anyone suffering a mental health condition that the can't control. Luckily for me as soon as I had the baby the seizures disappeared overnight, I went back to my original dose and it's been controlled again ever since.
There is light at the end of the tunnel though, It can be hard to get control of, and it will take the correct medication to do so, most of the time it's trying to find the right combination/dosage etc. The consultants will normally like you to try a medication for a few weeks to see how it goes, so you may have to be a little patient, but if you don't think something is working don't be afraid to say so, the way things are in healthcare at the moment you will most likely be left to fend for yourself unless you advocate for yourself, so keep fighting until you find what works for you.
Good luck OP, I hope you manage to get it sorted asap.
