Sheisha. No sane human being would kill his own mother. It’s a sickness. The boy told 3 or 4 different doctor’s weeks before the incident took place that he done it that he heard voices telling him to kill and them more or less told him there was nothing wrong
The reality is there is no sufficient help for people with mental issues all around the world to get seen in hurry and definitely the UK is as far behind from being sufficient as those other countries.
I have a friend from X country with mental problems and he have to wait months, sometimes over a year, before he is seen by an "expert"
I pity the boy and will pray for his poor mom.
