Better case scenario:
I have been trying to write this passage over and over, and no matter how I try, nothing seems right to me. I'll put it aside and try it again tomorrow after a good night's sleep.
It's not working well together, it's not coming together, it doesn't seem to work like I want it to.
Better case scenario:
I've been trying to find a dress to wear to the black-tie holiday party, and have tried on at least 30 dresses, but nothing seems right to me.
