Am I a perfectionist?

Perfectionist or completist whatever it is?
Am I a perfectionist?
Is this good or bad to be a perfectionist?
Honestly I don't know!

I was doing decoration yesterday.
Trying to stick stars on the ceiling of my bedroom which will glow in dark.
I printed out a reference frame of my own constellation.
I want to have a glowing ceiling in my room.
I put every star on the place which it should be.
I marked the symbol of every star.
Even named my own star.

But it looks like I doodled on the ceiling.
Made it even worse!

I supposed to have a beautiful romanctic ceiling.

What should do next?
Replace it? Or let it be.
And i had a sleepless night yesterday.

What's wrong with me?
It's just a ceiling, right?
But it is really annoying.
