Hi, I Have Lacked Energy, Had Intermittent Stomach Pain And

Hi, I have lacked energy, had intermittent stomach pain and diarrhoea in recent years, and have had high blood pressure lately. I seem constantly tired and fatigued, sometimes with headache, and my left eye has been twitching lately as well. Ive had blood tests including a check for diabetes, and had a colonoscophy/gastroscopy in 2012
