The frustration only gets worse. You are still young enough to reverse bowel training. I, too, was severely constipated since early childhood and became laxative dependant. I waited to go to a doctor. Now at 46 I amin a biofeedback program with a motility expert. Not real success but no worses. I do believe the sooner you get a work up the better. Pick a GI specialist with a motility expertise. Very few doctors know about the reality of this disorder. I had seen doctors at a younger age and got no where. good luck. You might want to try Perdiem. It is a natural fiber with senna and does work. I know because my case is very severe-- enema dependant as well.
