"To recognize" means that you are familiar with the subject or object being presented. "To realize" means that you understand what somethings means after a period of time where you did not understand what it meant. "Feeling depressed" means that somebody is experiencing immense sadness. The kind of sadness that affects a persons life. Lines are a shape. They are often used to separate things. Between the lines of a story may mean that the true meaning of the story is hidden in the words. If you need an image of a line I have a link to an image: http://www.politicalmetaphors.com/wp-content/uploads/2015/03/blog-shapes-Straight_line.jpg

I agree with Emir, except that I would translate 'to feel depressed' as 'depresyonda olmak' or 'depresyona girmek'. But, of course, it depends on the sentence where it is used.

You should put them in a context or you have to use a dictionary. Both of them have more than one meaning. I recommend Oxford Dictionary for Learners to you. http://www.oxfordlearnersdictionaries.com/definition/english/recognize?q=recognize http://www.oxfordlearnersdictionaries.com/definition/english/realize?q=realize
