It sounds like detailed thinking leading up to black and white thinking, like a small detail can spoil the whole. This is basically one of the bases of perfectionism.

This is not a diagnostic label, but I have myself found myself in trouble because I am a detail thinker. It is more a mental style rather than a disorder but in some cases it can create problems. Being not a detail thinker comes with its own set of issues.

Try to accept imperfection. Try to get and accept a greyscale. Not easy but possible. I have been able to in several areas of my life.

Good luck.
