Taking Lamotrigine, newly diagnosed.

So, as a bit of background.  I'm 25, had my first seizure over ten years ago, grand mal.  Had another two within the space of 3-4 years up until I was 18.  They never medicated me, had the MRIs and EEGs at the time and nothing.  

So, six years pass and August of this year I had a grand mal out of the blue after a heavy night drinking (alcohol has never brought anything on before) but also, the day after started feeling unwell and turned out I had a bad sinus/ear infection and in the two week recovery from the infection, I did have a few auras (generally the taste I get, but nothing after).  Since then, I've had auras on three occasions but nothing else, twice after drinking and once after being on Sertraline (SSRI meds), but again no effects of these.  

So a couple of weeks ago I saw an epilepsy specialist, he got an account of my last seizure off my partner and bam, diagnosed me with frontal lobe epilepsy (no further MRI or EEG yet).  He prescribed Lamotrigine.  

I also have an anxiety disorder, a lot of which stems from anything medical/health related. Which is making it very hard for me to start taking these meds,  I've read about the side effects and  the thought of something worse happening than a seizure terrifies me.  

It's worth also noting that with every grand mal I've had a good 45 minute warning (dejavu, then a taste/smell), so I am lucky in a sense that I've always got time to find a safe place/put myself in recovery position.

I guess what I'm asking is what would you do in my situation? I don't know if the fear of taking the meds is worth it? I mean, I'm worried they'll effect my work and life etc.  Whereas the only thing that's bothersome at the moment is my anxiety.

Thanks for any help!
