Similar situation that I'm currently in.

Bought a pack of sunflower seed and large bag of compost several months ago, that was what I considered as a decision made during Manic state. I felt so positive and intended to grow my own sunflower so that I could give it to someone during valentine's day in hope that it could patch things up.

Unfortunately, despite giving my attentions on my plants, my seeds did not sprout even after 2 weeks even though I placed my pot under the sunlight and generously watered it.

Soon after, my life began to get busy with commitments, work and coupled with depressive state. I simply gave up watering it or even sow a new seed for another attempt. I just hated it when it doesn't work out, and it became more of a burden than something that elevates my mind. I gave up on growing a sunflower for a particular someone because I felt I can't change anything after ruining her impression of me that could have been due to my bipolar state of mind.

Each time I refuse to water my plants anymore, I actually feel guilty for abandoning a task which was meant to test me in life. I got fed-up and turned the pot upside down to empty the soil's content.
