Seizures?

Hi to all of you. I have a similar situation to several people posting on this site. My eeg and MRI came back normal, but I have exhibited symptoms of seizures. For the past several months I have been having periods of blacking out. This has happened at home, at friend's homes, at work, even at the grocery store. I am told that I sometimes mumble, have a blank stare in my eyes, say odd things, or may walk around with no definate destination. I am told that I am either unresponsive or mumble in reply during these times.I am unconsious during these periods of time. I am told that this lasts 2 or 3 minutes. These episodes will come upon me suddenly with no warning. Quite a few of them have occured within a week of the start of that time of the month. I have had a long history of depression and anxiety problems, but nothing like the symptoms I am having now. I am on medication for my depression. However, there is also a history of epilepsy in my family. I have an uncle that had convulsive seizures as a child and the type where you blackout for a few seconds as an adult. I also had a cousin that had nighttime seizures as a child. Since I do have a history of depression and emotional problems, the first place I went to was a mental health clinic. Ihave been under stress lately. They suggested that I go to a neurologist. I went to one and they did an MRI and EEG. Those tests came back normal. The neorologist does not think it is seizures I am having. He mentioned something to me about still having my coodination. Does one lose coordination when they have epilepsy? Given the side effects of anit-epileptic medications, I understand the doctor's hesitation to prescribe something if he thinks it is more psychological than physical. I would like some feedback from others. Thanks TLH
