Follow your diet, stay away from alcohol and see your specialist often. Alot of what you mentioned sounds familar to Pancreatitis
. The diareha, the continuous pain
, the off colored stools. You are probably experiencing fatigue, mood swings, depression and/or extreme tiredness. My specialist told me it's exhausting being this sick and he is right. With your families help, you will be better in the future than you are today.
