TODAY
It's a cloudy day in Italy, but that <s>doesn't trow down my mood</s>.
What are you trying to communicate here? Do you want to say 1) the weather doesn't affect you or 2) that you're not going to let the weather negatively affect you?
If 1) it sounds more natural to write something like "...but that doesn't affect me", "...but that doesn't change my mood" or as Debbie suggested "...but that doesn't dampen my mood".
If 2) you can write "...but I didn't let it bring me down (bring me down is an idiom meaning make you feel sad or melancholic)
So I decided to <s>cook by hand some gnocchi of potetos</s> make potato gnocchi from scratch (from scratch means from basic ingredients), but now my kitchen is a big mess <s>whit the flour oround the whole room</s> with flour everywhere. Anyway, the gnocchi were good and delicate. I was very surprised <s>for this thing</s> by this, because I'm not a great cook<s>er</s> but <s>more</s> an excellent eater ahahah. I love eating. I love food ahaha.

My final edits for something that sounds a little bit more natural:

Anyway, the gnocchi were good and delicate. I was really surprised because while I'm an excellent eater, I'm not a great cook. I love eating and I love food.
