Oh, I'm sorry to hear that you're having a challenging experience with your manager. It can be incredibly frustrating when our working relationships aren't ideal or when we feel unsupported.

While I can't say for certain if your manager was sent by the Devil (I don't have access to that information), it's understandable that you may feel frustrated and overwhelmed. Dealing with difficult managers is never easy, and it can take a toll on our well-being.

Rather than dwelling on negative thoughts, perhaps it would be helpful to explore ways to address the situation proactively. Have you considered discussing your concerns with HR or seeking guidance from a trusted mentor or colleague? Sometimes, reaching out for support and looking for strategies to navigate difficult work environments can make a difference.

Remember, not all hope is lost! There are often resources available within organizations or even outside of work that can provide assistance in dealing with challenging managers. Hang in there, and remember that better opportunities may come your way in the future!
