Celiac sprue?, IBS?: It is difficult to tell what you have but seemingly you are having much trouble. Being 6"2' weighing 105 lbs is significantly underweight. I recommending see doc for eval of possible celiac, significant thyroid/endocrine disease, or very severe ibs/irritable bowel syndrome etc... Other condition such as crohns' disease, HIV enteropathy etc... Can pose much trouble as well. Consult doc. Good luck.
