I just want this to stop.

I have had this issue for several months and I don't know what is causing this... Okay Right under my rib cage.. But in my stomach sorta it hurts. Every night I can't really sleep because it hurts so much. My mother suggested I start eating a lot more fiber.. But whenever I see food, I'm not hungry for it at all. I've lost 3 pounds in the last couple of months and it kinda shows. I hate to bother you about this, But I can't go to the doctors to find it out. Can you please help me?
