Is it all in my head? ( no pun intended)

Im a 43 yr old male, diaganose with simple and complex partial seizures. My history is congenital hydrocephalus and a congenital heart condition, mitral stenosis. Both conditions are stable, I no longer have a bad heart valve but have a mechanical heart valve which requires me to take blood thinners (Coumadin). As a result of the blood thinner, i develped a cranial hematoma and had lapsed into a coma for a short time. I had a "craniotomy" 3 times emergently that night but recovered after about 2 yrs getting myself back on track. I have an abnormal EEG with spikes and "fading" (?). My symptoms I didnt asociate with seizures until my doctor told me that is what they were ( one-sided numbness in my right arm and leg ( the hematoma was on my left side of the brain). I get nausea and a metallic taste and my speech slures and my tongue shakes and quivers, especially if I dont get enough sleep. I am totally aware of where and when I am at the time but feel "disembodied". I also have flashing lights that start in my peripheral vision and last for 20 min with no headache afterwords. Are thise common for seizures? Am I "normal"?? I just feel like its "all in my head" sometimes. I count myself fortunanate that I have thise symptoms only mildly and not too often but still, it doesn't seem to "fit" as to what I percive epilepsy to be. Please write back and talk to me! Thank you so much!
