You see, for awhile now i've been struggling with my weight and appearance. For about two weeks i ate very little food and now i tend to binge a lot, but it makes my stomach hurts like hell... why is that? 

Also whenever i took a deep breath when laying on my bed or sofa i felt like my ribs pinched my insides, making my abdomen and lungs hurt. It's almost like i was been squeezed, making me feel a quick and sudden pain, that sometimes takes my breath away. What is the source of that ? what should i do to make it stop?
