Question

Is this sentence OK? Or how would you say?
(an advice etc.)

I needed to say it to you as a friend of yours.And this;
I needed to say it to you as your friend.

Answer

For simple past?

I think it's better to say :
I needed to say it to you as you are my friend.

or just simply replace "as" with "because". Both are acceptable.
