unhapiness

My dad was admitted in medi clinic about two weeks ago with the problem of being dizzy and loosing a bit of eyesight. He stayed at the hospital being just normal the way he was and got discharged on Monday 30 March 2015 and together with some medication that he doctor gave when he was discharged. The next day 31 March 2015 a while after taking pills that the doctor prescribed a while after started to complicate and couldn't talk and decided as a family to take him back to the hospital, by that time the blood pressure has gone up and he no longer breathed normally, we left him there at the hospital. In the early hours of the morning we were called as the family to the hospital, I got there first with my brother and one of the nurses in the emergency ward said to us that sorry we had lost my dad and we must go to the ICU so that they will tell us what happened. When were went to the ICU there nurse said that he came back and breathed, and they put him on the life support. Since then he never can back and they put on breathing pipes whilst they knew that he was never coming back so I think that the all wanted to make money whilst he is still there.
