The presence of severe abdominal pain and tenderness, accompanied by vomiting episodes in a 15-year-old female, strongly suggests a diagnosis of appendicitis. This condition is characterized by inflammation of the appendix, which typically leads to acute abdominal pain that often begins around the navel and then migrates to the lower right quadrant. Accompanying symptoms often include tenderness in this area, fever, and nausea or vomiting, which align well with the clinical presentation described.

In this age group, appendicitis is one of the most common abdominal emergencies, and the classic symptom pattern aids in its diagnosis. Other conditions like ovarian cyst rupture or gastritis can also cause abdominal pain but would usually present with different symptomatology or additional specific signs. Cholecystitis, while possible, typically presents with pain in the right upper abdomen and might involve a history of gallbladder disease or fat intolerance, which isn't highlighted here.

Therefore, due to the combination of the clinical features and the typical presentation associated with appendicitis in a young female, it is the most likely diagnosis for this case.
