Major respect to the NHS and all that were involved in the care of your son at the time. I have had much more than my monies worth from the NHS over the years and can't thank them enough.
Recently there has been a very sad incident where a local Paramedic went missing, his personal belongings were found at a notorious suicide spot and he was recovered a few weeks later. Sadly, too many front line workers are suffering from PTSD,
mainly because it is not picked up on in the early stages of the illness. With massive cuts to the NHS budget and restructuring of front line services, these sorts of incidents will increase until something is changed.
If we personally know of anybody in this area of employment, keep and eye on them, just in case.
I'm pleased that your son will make a speedy recovery Saxon Axe, send him best wishes from my family and me.
