Could my anxiety cause epileptic episodes?

I have been suffering from anxiety for the last 3 years and it has become severe in the last 6 months due to the birth of my son. As a result, I am getting next to no sleep and feel like I am running on empty every day. When it comes time for me to go to bed at night, I feel extremely anxious - my head spins, my breathing becomes fast-paced, I feel nauseous, I feel my sinuses go a bit like they do when you have a head cold and it feels like I have a sort of dripping down my throat, I can actually hear my brain 'buzzing', sometimes I dart my eyes about in my head uncontrollably and then with no warning I feel this wave-like sensation in my brain that only lasts about 1-2 seconds. Immediately afterwards, I feel no anxiety, although I feel extremely tired and can sleep within minutes. Sometimes I feel this same wave-like sensation when I concentrate too hard on something. Is it possible that my anxiety could be causing some sort of epileptic episode?
