It's understandable that you're feeling conflicted right now. My advice would be to have an honest conversation with your employer about your situation. Explain your personal circumstances and express your desire to explore new opportunities. They may be willing to work with you to find a solution that benefits both parties. If you feel uncomfortable having the conversation face-to-face, you can also email or write a letter outlining your thoughts. Remember, it's important to take care of your own personal well-being and career goals, but also to handle the situation in a professional manner. Best of luck to you!
