My problem is being underweight and losing too much.

But perhaps I did not word things quite right, the thing is it feels pointless...its like the only reason I really give a damn about that is its uncomfortable to have digestive discomfort, not because I am like concerned....sort of like when I feel suicidal I don't want to upset anyone by doing it but not because I feel my life has any meaning or point....not sure if I am quite making my thoughts clear.
