I so feel your pain and frustration. I have redundant tortuous colon, constipated all my life (74) now. I used to go almost daily, but hard and small. Recent colonoscopy only showed some thickening of Sigmoid colon wall ( muscular hypertrophy) I've done all the 64 oz of water, fiber, exercise, Miralax 4 x's a week . It's a balancing act to not get cramping and diarrhea. I too have had to cancel trips, and live alone and it's affecting my social life, and mental health. And yes, people don't understand , nor do they want to hear about it. Best to you! Bobbie
