Your friend will make it hard for you to learn Turkish if he does not use the correct Turkish letters.

Here is my attempt at the translation

Firstly thanks to a Brazilian friend I saw you.

I never spoke with him/her, he/she only apparently added me (as a friend). From their (facebook) page I found you.

A 41 year old woman.

(I have to go to lessons now, so someone else can finish this) 

I don´t know her. She just added me as a friend. That is how I found you. I asked you for friendship.
