I feel sick...how do i feel better?

The right side of my stomach area hurts, like where my liver and ascending colon are, but it's not like intense pain, it just feels sore. I feel like throwing up right now...and it doesnt help that im emotional now too because i miss my boyfriend who never makes time for me anymore...im tired of suffering emotionally, mentally and physically. What do i do? Nothing ever makes it better. All i do these days is hope to God that i have cancer because i just cant take anymore of this life...
