I listened to him in a podcast recently when he said he had real issues going out. I thought then he sounded anxious.I think it is some kind of breakdown plus break up of his marriage, perhaps with a side order of worry about his mum. He has completely overworked himself. He has taken on a lot. He was relatively unknown recently. Now on everything, all tv channels, adverts, radio, personal appearances, and all prime time. I can understand making hay whilst the sun shines but being completely overworked can’t have helped. Who knows. Best wishes to him.
