Am going through a tough time at work and it's really starting to take over my life. I constantly worry about being fired for underperforming. I manage a company day to day and all my experienced staff are leaving due to hating my boss, the director. She doesn't see this as an issue and constantly makes me feel like a failure. The problem is I can't stop myself from turning everything into a catastrophe and imagining the worst. At this rate it will become a self fulfilling prophecy as I feel too fried to do much of anything. I can't switch my brain off when at home but at work it seems to stop working, like I freeze up. I really struggle to sleep and a lot of the physical symptoms like sweating and palpitations are back. I am wondering if anyone has been through something similar and if they have any advice please?
