Well, they can be very closely related inside us. Even Scripture talks about the (Holy Spirit) dividing the thoughts and intentions
of the heart ! You know, as most of here at PC know, that relying upon feelings can really mess up our day. We must rely upon what we know to be fact (truth) to get through many negative situations.
Remember the quote, Don't doubt in the dark what you knew to be true in the light? I think that addresses this very thing... what we knew/know in the light is what we understand as truth, factual..but the dark comes and when we can't "see" the truth any more, our heart/feelings begin to change it and we become confused.

Plus, for you right now fuzzybear, the meds are trying to balance your system out... don't think too deeply or fear things, ok? (((hugs)))
