Hey there,
Sorry to hear about your edjabacation troubles
Seriously though, I would not underestimate the effects of stress on the bodies higher functions. If you have been in stressful situations for the
last little while your body may be going into basic survival mode, That is just trying to process the negative or less enjoyable parts of your life is
work enough for your brain.
For what it is worth, I have always found that being in a stressful job means that you have to have an equal amount of time dedicated to the opposite.
That is some place or activity that recharges you after doing 8 or 10 hours of a stressful job. For me it's returning to my home in the country
and walking the dogs up back through the fields and trails. I know difficult if you are overseas and such.
I recently saw a story on the discovery channel that proved that university students concentrated and problem solved much better in peaceful quiet,
stress free surroundings. Something to think about.
Hope this helps somehow and hope you get those synapses firing once again.
My old philosophy proff. recommended reading, reading , and more reading, to keep the mind sharp and to keep learning new things.
peace
