Visit my nephew

Today, I was visiting my nephew named Brayan. He is two and a half years old. He is blonde with blue eyes. I'm in love with him. He makes my day happy/ he makes my day.
I am studying out of my city and when I return, I'm going to visit my family.
Today is my last day in my city, tomorrow I go back to the routine. I have exams until July, I hope everything goes well.

out of my city/my city-- no estoy seguro como traducir esto, no lo decimos así pero entiendo

He makes me happy day. 

- He makes my day

- He brightens up my day

Good luck with your exams

Visit my nephew

Visiting My Nephew

Today, I was visiting my nephew named Brayan. He is two and a half years old. He is blonde with blue eyes. I'm in love with him. He makes my day happy.
I am studying out of my city and when I return, I'm going to visit my family.

(better say: I am studying away from home and whenever I return, I visit my family.)
Today is my last day in my city and tomorrow I'll go back to the routine. I have exams until July and I hope everything goes well.

Muy bien!
