It's a scary thing to have happen, I know. It's happened to me before. Actually, last week. I was at work, where I've worked for over 4 months and I was walking from my station to the washroom in the back of the store and all of a sudden, I had no idea where i was or why I was there. I kind of spun around and tried to connect with something and then someone said "hey, what's up" and I just as suddenly came back to myself. It was a short episode but scary as hell so I can't imagine what it would feel like if it lasted a while like yours seems to have.
Big hugs hunny. Let me know if you want me to call you this afternoon. It might ground you a bit. I wanna help if I can.
love ya
