Am I Just Losing My Mind?

In this episode, Dr. Betters answers the question, "There's someone from my past I want to let go of but can't. I've been praying to God for the past 3 years, asking He make me forget her and help me move on, but nothing has changed. The smallest things will trigger memories. I'll see her face in dreams, so clearly, like looking at a photograph. Is God telling me not to let go of her? Is it a demon distracting me? Am I just losing my mind? I've looked everywhere but can't find answers. I'm just so conflicted and don't know what to do."
