Hi
then you are either blissfully ignorant or foolish if that is even near your major fear.
Pumphead is not permanent and like all things which can impair your capacity you can train around it. I'm a software developer too (PHP, some Java, Oracle back ends) and while soon after surgery I would make silly mistakes in maths and be confused it passes.
Now, if you fell off the gutter and smashed your head or had a car accident or a stroke ... the list is nearly endless ... you would face similar challenges. There were challenges when I went back to work, but by a few months I was really on top of it. Then I hit a real bump in the road and I just couldn't give a **** about stuff like that anymore.
well if you believe in God then you should accept the decisions of God and not beg God to change Gods plan.
Maybe Ganesha or Shiva will be different, but Jesus prayed at the last supper and still wound up on the Cross suffering despite his prayers.
If you wish to pray then pray to your God that you have the strength to live as God dictates, not as merely you desire.
