Help understanding doctors letter -EEG results

Hi there-so I'm really looking for some help in making sense in a letter I've received this morning from my neurologist if possible. So, to give you a brief background, I had a major seizure end of January-first (known) time this has happened-no warning signs and completely out of the blue. Had a few split second blackouts about 4 weeks prior and approx 7 years ago I had a "suspected" seizure (no witnesses-found unconscious). My MRI, CT and angiogram came back fine. My results for my EEG arrived today and the doctor writes as follows: "It showed there is an excess of irregular mixed frequency slow activities over the temporal regions on both sides, and there are occasional sharp waves, particularly in the left hemisphere. It suggests that there is an increased focal susceptibility to seizures." He goes on to say that if it happens again I need to go onto keppra but otherwise we'll see her in 6 months time. I feel totally left in the lurch with this as I don't know how to interpret these results-does this mean I have epilepsy or simply that I am prone to such occurrences due to the frequencies of my brain? I feel as though I've been left to put the pieces together myself and with 5 young children and a job/house to run etc it's very worrying. I'm struggling to cope without my licence, which has been the biggest blow to me-not just practically but in terms of my confidence and self esteem because it's taken my independence away. I live in a rural area so it's really hard. If anyone could offer any advice on how to best interpret these results I'd dealt appreciate it. I've booked an appointment with my gp to discuss but even that's a two week wait.
