i should said that i have finally met the worst day from my whole pratical training period everything started to go wrong from morning to the night. there was one moment i  realluy feel like want to knock my head to the cupboard as i have had enough of the situation.  along all these days, i never cry for my works, but today i have hit my endurance limit that i burst out of tears after i try to vent out everything to my dad.  useless me, that's it.
