Could this be Seizures?

I don't even know where to really begin, here is the basics. In Dec. 2005 I was in the bathroom with a stomache bug. I began to feel overheated,tingling and numbness,light headed, Sweat terribly, and feel like I was going to throw up. I almost didn't get my sweater off before I passed out. I remember hearing (not feeling or seeing) my head repeatedly hitting the wall in a corner of my bathroom. When I was finally able to get off the floor. I had to call my fiance to help me to the bedroom which was across the hall. He put me in bed and later that night I tried to get up again and the same happened except I made it to the couch before I hit my head again. I don't remember the episode at all on 1/30/06, my fiance said he found me sitting indian style passed out with my head on the sidewalk. He says I may have been there for up to 20 mins. He said when he tried to get me up I continued to babble and make no sense for about 10 mins. I don't remember any of that. I do remember feeling so scared and confused. Like I was asleep and suddenly I totally lost where I was and how I had got there. Both times I hit the right side of my head. above my eyebrow the time in Dec and my Temple and Ear area in Jan. When the dr asked if anything like this had ever happend b4. I remembered that when my Great-Granmother was dying, the family was gathered at the nursing home and then I remember my sister standing over me. She was yelling are u ok? I told her get off me. I was panicked trying to understand what happened. After that I drank juice and ate crackers. I started feeling sick to my stomache and tried to make it in the bathroom to throw up. My hand wouldn't let go of the handle and my arm began to jerk and then I remember sliding down the door as everything went black. I never got that checked out because I thought it was due to stress from loosing my G-Grandmother, we were close. I also had a car accident at 16 and the left side of my head went thru the side window on my left side. I had three layers of stitches, 48 in my temple area and a little into my hairline. they also said they found Incomplete RBBB. but the cardiologist says that is normal for my age (28) and that he doesn't think it's my heart but will do the tests anyway since i have alot of chest pain and palipitations. My MRI had a small spot on it that they didn't feel was clinically signifigant and my EEG showed nothing, though during the fast breathing, I felt almost identical to what I felt in Dec. also I am forgetting conversations I have had with people, and this sounds SO stupid but I looked back at my son's agenda and I even forgot how to sign my name since Jan. I am forgetting a letter. I don't know what to do or who to see, no one seems to have any answers. The Cardiologist says after he completes the testing he will send me to Neurologist. He said from the moment he met me that he thinks it's seizures. I had a 29 wk old preemie a lil over 3 years ago and she had seizures too, so they seem oddly familiar and I use to know before she would have hers sounds weird huh?I have also been having my left hand draw up whenever it wants like someone else has control over it, and my fingers on left hand begin to twitch around alot, left eye twitches alot, and left side of neck. What is going on and what should I do? Any suggestions? Have any of u experienced anything like this? Thank U for listening.
