love and fear

I am reading a book named 'Talking to the God'. It is said that there are just two kinds of emotions of the human being human emotions: love and fear.
Love emotion can let you live happily, think positively and successfully. In the other opposition On the other hand, fear emotion can lead you to the envy, hate and failure.
Somedays I feel that felt like I was in the fear emotion. Because I'm afraid of failure, I can't couldn't try the ideas I thought express myself. I know I must get out of the that trap quickly.

I made these suggestions because I think they sound more natural, but they don't change the meaning.

One thing that I'd like to mention is that your tenses were not in agreement in the second section, and that made the meaning a bit unclear to me.  'Somedays I feel' is present tense and then you say 'I was in fear' which is past tense.  It makes things confusing, so try and keep everything in agreement.

And remember, "The only thing we have to fear is fear itself."
