Sorry to hear about your accident! Everyone covered on how to avoid this in the future well. Also just be sure to inspect any old equipment before use. I know we get into a rush but seeing any small defect ahead of time can save a life. I've been shocked several times but never full on zapped. Heal fast! Give your dad time, he may have focused on the house as a way to control his fear that you had been seriously hurt. After all he can fix the house, unless he is a doctor your care was out of his hands. Then once he knew you were not going to die comes the "why did you make me worry" part lol.
Then again he could be a jerk. I don't know him but try to give him some consideration that he might just be freaked.
