My daughter has times when she feels light headed, like she's going to faint. It can sometimes last for hours, and she has to stay lying down. She also has something her mental health team call a stress disorder, where she falls to the ground in a non epileptic type fit if she gets very stressed or frightened. She also has moments when she is clearly 'not in the room' and is unaware of this happening until she realises that she has missed some of the conversation. Is this the same thing?
