The correct phrase is "feel confident," without the word "of." So you would say "I feel confident" instead of "I feel of confident."
I don't quite get what it is that you are asking. Would you re-phrase the question?
that you can feel it in your body
This phrase means a rage that is building or is appropriate for the situation. It means what one would expect to feel considering the situation.
The correct phrase is "Words can't explain how I feel about you." This version uses "words" in the plural form, which accurately conveys that no combination of words can fully express your feelings. The phrase emphasizes the depth of emotion that transcends verbal expression.
Say, "How do you feel about me not being there?"
That something positive that you had expected to happen had failed to do so, or that someone had failed to help you in some way when you had expected that they would do so.
There are six syllables in the phrase "why should feel ashamed."
The phrase is not grammatically correct as written. However, if you say "Whenever you feel like it, come" then you mean "come to the location whenever you feel as though you want to."

It depends on the subject the two people were talking about. However, saying, 'I am sorry you feel that way' is seldom a narcissistic phrase. Two people can have opinions on many subjects they are passionate about and what that phrase generally means is it is a stalemate and neither side is giving in so the one person who says they are sorry you don't feel that way is simply letting you know they still disagree with you.
Sounds like "Do you feel like I do", that was a phrase from a Peter Frampton song by the same title.
