Chai tea.

I like chai tea.
It is a special drink for me, so I drink it on special days.
For example, I drink it when I am very tired or very sad because it gives me peace of mind and gives me energy.
The taste is sweet and spicy I had .
However, the internet says that the one I had is not the real one.
At local chai tea place, the chai is not too spicy and very milky one.
I want to drink that kind.

You are right, Aki.  Chai, from what I understand, is an Arabic word (maybe) which simply means "tea" and is served in Arabic and Turkish restaurants.  Correct me if I am wrong to whomever may be reading this.  It is basically a black tea, from what I understand.  What you are drinking is a spiced chai.  I like them both.

For example, when I was very tired or very try not to repeat very back to back. It is OK to write it as you did however with proper grammar you would not really want to do this. sad, it makes gives me peace of mind and gives you are repeating again here as mentioned above energy to me.
