I do not know what this is please help!

I was getting ready for bed and started to put on a movie ( as I usually do), when all the sudden I felt very dizzy and just strange. I thought wow I must really be tired and got in bed (not sure if I remember actually getting in bed).
Next thing is I only remember "snapshots" of the next few days.

• On day one (after my kids managed to get me out of bed) I had very slurred speech, double vision, lack of balance. somehow I thought nothing was wrong with me I told my kids I was going to work (dressed myself and even brushed my teeth). Scariest part is I would have tried to drive had they not stopped me! They called my sister and I was taken to the doctors and they sent me to the E.R.. Lots of tests where done (pregnancy, drug,cat scan) all came back normal. There was talk of seizure. We where there from 10am till 7pm I remember one "snapshot" of this whole time. most of it I slept through.By that evening the slurred speech and balance was better but I was very slow and seemed confused.

• The second day I slept all day. I dont have "snapshots" or anything from this day.

• The third day I remember some of. I was alone on this day and I slept most of it waking up to answer the phone a few times I remember being really sore everywhere. I don't remember the evening.

The next 3 weeks are are a total blur I remember very little, and very foggy. In fact I feel like this all happened last week, but I received a statement from the hospital and when I saw the date I had to look at the calendar cause I didn't believe it, what happened to the rest of the month? and what have I been doing?

I had some bad anxiety during this time that was different then usual for me I just would begin crying and couldn't stop. I've had headaches which I never get (I do get migraines after times of stress (the type that involve vision loss, hand numbness, confusion) no ability to concentrate, or problem solve.
My kids though teens have been feeding themselves they say I haven't made dinner all month! I never even realized until today.
Prior to this event things have been very, VERY, stressful. I knew things where building up cause about a week before this happened I started getting the facial twitching. This time my left eyelid was pulling shut though instead of the usual lip or under eye twitch. But I haven't had any anxiety for over 6mos and before that probably another 6mos.
Anyway, just wondering if there are any possibilities.
Oh yeah, my doc's conclusion is that it wasn't really brought on by stress and she thinks that it is a "drug flashback"! This seems really far fetched to me especially since I haven't had a drug problem in 12 years and never ever experienced anything remotely like this in my 8 MOS of heroine use 12 YEARS AGO!
Please just looking for other opinions. 

Thank you
