Firstly may I say I am so pleased that your wife got a diagnosis, albeit not a very pleasant one. I hope she continues to do well. Secondly, please do your best to rest now. I know this is difficult, but do try.
Waiting for so long in A&E itself is so stressful. You know, it is amazing how we find this kind of strength when a loved one needs our help. We seem to go into overdrive. You read quite true stories of people moving cars physically on their own, and running as though in a race when normally their strength is so little. I think it is an inner force that gets our adrenaline going with such a rocket, that we can and do anything for the time it is required.
When someone perceives a life-threatening situation, epinephrine (adrenaline)is automatically released into the bloodstream (for more energy) and alters our bodyís system. Our bronchial passages dilate (pumping in more oxygen) our heart rate increases (giving us more endurance), our pupils dilate (helping fine focus, but causing tunnel vision) auditory exclusion and Tachy-psyche occurs (the misperception of the passage of time).
Your whole body goes onto alert and the flight or fight syndrome comes into play. You needed to fight and your body responded to the situation. In our "normal" daily lives, this situation thankfully doesn't come into play so our bodies and minds don't gear themselves up to do this all of the time. Our minds and bodies would burn out in such a short time if we had to live day by day like this. You had one aim and your goal was to "save" your wife, and your body responded to your mind and did just this.
Gosh, I have gone a bit deep, but I find this type of thing very interesting. I myself think it is a truly physical and mental reaction, but I do know others who have a religious faith believe that it comes from their God and their beliefs. Whatever way you look at it, it does happen and thank goodness it does in times of such stress and trouble.
The thing now though brend is that your body will really stop itself in its tracks and say "hey, what happened there". Try to take a warm bath and relax and go to to bed, even if not to sleep, to rest your body completely and also your mind. I hope that you will not suffer too much from the after effects of this, and that you do get time to take it a bit easy. Regards to you and your wife.
Plese take care.
