derealization

[Citizen T]

I have been told by a therapist that I have derealization, but she isn't sure why because I don't have the social history to cause it.  Everyone seems to say this is caused by anxiety, but that seems ridiculous because I don't get physical signs of anxiety like racing heart, short of breath, etc.  plus it is constant..  It's nothing more or less than the way my head feels.   I will try to explain... everyone has had an occasional blood sugar drop, but when I do I can't tell the difference in that and the way I already feel.  I often end up taking my sugar level every now and then when I feel very bad because I'm not sure what is what.   The way I feel is almost exactly the way you feel when you breath nitrous oxide/dental gas, and at different times of the day the gas is turned on high, medium, or low..but it's always on.  I just feel this bizarre lightheadedness and spaced out feel that never goes away.  I haven't dropped dead yet, but there have been times that it was so bad that I just threw myself onto the floor and had to just let it ride it'sself out, with bizarre cartoon like visuals of the real world and one headrush after the other, more or less fading in and out of logical thought..   I can be falling asleep at night and wake up multiple times as I'm falling asleep with this profound feeling inside my head of whether I'm here or not.   I have been put on full disability because of this, and I require full support from my family for all my requirements,  I say that to tell you have it has effected me.  

My mother is schizophrenic.  Do you think this has something to do with it?  What drug should I take?  I have a prescription for Lamictal and ativan, but I'm afraid of both especially the ativan.   Truly most people sense that I might be 5% awkward when talking to me, but I can usually fake it pretty good.  But inside my head, is pure hell.  It's just like that movie "Numb" with Matthew perry,  only mine is worse.

You are describing something that must be treated by a qualified psychiatrist is not a general medical doctor. You should not be treating yourself with regard to the medications you take because many may have tried to write one and it has to be done systematically. When you see your psychiatrist asked him or her about starting with a simple anti-anxiety drug.

If you forget everything I said above, which drugs are NMDA receptor agonists?

Please do not take this the wrong way. I would look into schizophrenia. Seeing that your mother is. Schizophrenia can pop up just about any time in life and you don't even have to have symptoms until you have a psychotic break. I know from experience.
As a side note: Do you get enough sleep. It sounds as if you don't. When I was younger I was going through the dizzy spells and head rushes. The doctors put through a sleep study, had me hooked up to machines while I slept. They found that I wasn't getting enough sleep and that was causing the dizzy spells. So now that I am older I know when I have these feelings I really need to get some sleep.
I hope all goes well and you can figure this out.
