“We are all a little weird and life is a little weird, and when we find someone whose weirdness is compatible with ours, we join up with them and fall in mutual weirdness and call it love.”

Hi! I need to improve my english for my job. The most difficult thing/part for me is to differentiate the prepositions. For example: when i should use "in", "at", "to" , "from"...

 

Today is a bad day!

In Italy, today is a bad day. This morning there was a terrifying earthquake in Emilia Romagna, the region in which there is Bologna.
The main zone(s) that (were, because it's multiple places) involved (Involved works here, but it would be better to say, greatly affected, or just "affected) were Modena, Ferrara and their provinces.
The eartquake was so strong that I felt it, and I live more than 250 Km far away (optional to add, away from the (epicenter=point where the earthquake originated) of the quake). There have been 15 dead persons 15 people have died from the quake (workers in sheds) and hundreds of injured ones were injured. 
In Italy there is a proverb "Piove sul bagnato"(english equivalent expression="When it rains, it pours")(literally It rains where it has already rained) It means that problems go where there is already a problematic situation . In this beautiful zone/region of Italy, the birth-place of Italian Comuni and Seignories in the Middle ages, earthquake started to hit 15 days ago and (never stopped/haven't ceased) since then.
First of all I think of (all the) local families without (a) home. I'm worried about that.
Besides, I'm also worried about Modena and Ferrara's artistic heritage we have lost!
It's a tragedy!
