What is the value of feelings? Listener question

Need a bit of clarification around feelings/sensations. 

Is the only real value of them only as feedback information to the system? To observe them and feel them when they arise?

I see a tendency to (especially with the ones where resistance is still very strong) to bite into them, dissect them, search what caused them, etc. But listening to the last webinars on the WELL course doing  this is totally in vain.

Feels like my mind jumps in the middle of it and wants to get rid of it which makes all together even worse and prevents the body from just noticing and feeling it.
