Could these be seizures???

Hi, I actually joined this site becuase my 21 month old son has recently been diagnosed with epilepsy. Through my research, I have discovered that perhaps I might actually be having seizures as well. I am hoping that some of you would read this long history and tell me what you think. I feel like I am going crazy and a bit of a hypocondriac. I do not want to mention this to anyone becuase I feel like I may be a little crazy. But strange "things" have happened to me since I can remember, and reading some of the forums and blogs from people here and now knowing about the various types of seizures, I am truely wondering if these strange "things" are actually partial seizures. Ever since I can remember (I am 28) I have times where I begin to feel very "removed" as if I am inside my body. I am still aware of what is happening, but it seems like it's in a "distance." I get little sparkles of light in my eyes and voices are very faint. I get a sense of de ja vu and just feel so inside myself. I can hear people talking to me and I understand them, I don't get confused, but I really can't talk to them. My daughter goes crazy when this happens! I feel like I am daydreaming, and I realize it but can't pull myself out of it. Then all of a sudden it goes away. Sometimes I feel like I am going to pass out (really light headed) and get a strange metal taste in my mouth. Sometimes these tastes and daydreaming things go together. In addition to these feelings, I have periods of irregular and fast (120) heartbeats. I have seen the cardiologist several times, but my heart is fine. I have also seen a neuro because of some "shakes" that occur on and off on the right side of my body. These things can all be unrelated, and I would never have even thought that I possibly would have considered any of these things seizures until lately. Please share your advise! Thanks!
