It's nice to see the relationship between the mind chatter and the bodily sensations. In fact, next time you check your email or facebook, be mindful of the body. You will likely pick up some reactions. You'll get better at feeling body sensations with practice.
Also, what Jhana4 said is good.

With some quiet thought you will come up with antidotes for other uncomfortable emotions.
We should clarify that there's a difference between "bodily sensations", "feelings", and "emotions."
When practicing the Four Foundations of Mindfulness I think it is important to understand those distinctions. Thus, there are:
1. Body sensations
2. "Feelings" of pleasant, unpleasant or neither. ("Vedana")
3. "Mind states" such as desire and aversion.
"Emotions", are understood to be merely composites of these three things, and it is helpful to see them as such.
