Iv'e been diagnosed 'Atypical Depressive' in addition to my bipolar. One of the symptoms is physical fatigue marked by a sense of weights pulling the body down to the ground. Sometimes standing or sitting up straight seems so difficult. The worse my depressive mood the worse this symptom. And the worse the sensations the worse my mood, and so on.

My pdoc has me taking yoga at the hospital in an effort to learn techniques to stretch, breathe, and meditate to try and alleviate this really odd condition. It hasn't made the sensation go away but it has helped. Naturally when I'm in public the sensation can be constant. I can't very well break into downward dog in the middle of the grocery store, can I? hahaha
