If and it’s a rather big if he has Bi-polar than I am amazed that his wife, parents and those close to him were unaware.
It is an illness which is very visible and difficult to mask
They might well have been aware GrannyGravy13 but not everyone can come to terms with the devastating effects of bipolar illness and find it impossible to acknowledge or discuss.
It's completely out of anyone's power to put a stop to an episode, manic or depressive, bar a chemical cosh which doesn't happen nowadays except in the most severe cases where sectioning is involved. An episode can be masked with people assuming the person is just being arsy or out of character excessive, not associating it with bipolar at all. And when the episode finally abates the desire to get back to "normal" is overwhelming and nothing gets mentioned for fear of triggering another bout, walking on vertible eggshells lest something kicks off again. It's horrible.
I don't know if this is the case with Mr. Murrell but if so I have a lot of empathy for him and his family.
