Last night, I suddenly came up with an idea to organizinge my house.

You can't say what you wanted to say how you said it, because you need to mention that you thought of what you wanted to do.
You could either say "I suddenly came up with an idea to organize my house," or "I suddenly thought about organizing my house," or"I suddenly decided to organize my house"

I wonder why suddenly I have aI had a sudden impulse to do something at midnight.

Sounds better this way - also you have to say "had" instead of "have" because your impulse was in the past, so you have to use past tense

And this morning, as soon as I waoke up, I organized athe fridge.

You have to say "woke up" instead of "wake up" because of past tense. You already woke up.

If you say "a fridge", it could be anyone's fridge. When you say "the fridge" or "my fridge", that means you are talking about your specific fridge.

After cleaning up something, I always become feel refreshed and I like this momentfeeling.

I think "feeling" sounds better than "moment" here, because you are saying that you feel refreshed.

In my house, there areis so much stuff, so I want to aim for a minimalist lifestyle by selling or throwing things away it.

"Stuff" is singular, so you should say "is" instead of "are"
