Hello.If you have abdominal pain
and lack of energy for many months/years you should be evaluated by a specialist in digestive.Crohn's disease is a possible diagnosis, but to confirm this diagnosis is necessary to do a colonoscopy
Your symptoms may be due to pancreatic pathology, intestinal pathology...
Go to specialist in digestive as soon as possible.He will request additional tests to establish right diagnosis and treatment.
I wish you good health.
