My best friend is going through a really tough breakup and she needs me right now. She has been calling me every night crying, and I feel so guilty every time I have to cut the conversation short to study. My PMP exam is next week and I am nowhere near ready. I feel like I am failing as a friend and failing my own career at the same time. I got so torn last night that I actually had the thought that I should find someone to take my PMP exam for me so I could just be there for her. What would you do?
