Your feelings may be pointing to a time for reevaluation.. 

When you are in a place with another that has negative emotion, to the point that you can no longer remember what happiness felt like in their presence, it is well past the time to step back and reevaluate this relationship.  Sometimes your body has been telling you and you just haven't gotten the clue.  That physical feeling is not always logical, but when it happens, back up and listen.  Open yourself to the possibilities of having a different relationship with this one, or none at all.  You can decide.

You need no one in your life that takes you to a painful place..
