Listener question: is it my fault?

Listener question: I suppose I’m again in the thick of it (triggered by painful events at work) with overthinking, panic, hotflushes, insomnia, crying meltdowns. I thought I could be more resilient by now. I need again a lot of emotional support and tender loving care. But I perceive the world as brutal at the moment and it doesn’t help to know it’s all thought created. Is it all my fault?
