Hi ineedhelpplease, I can relate to the situation you describe since I have treated and corresponded with a number of college students over the years. The stress of the first couple of years living away from home, usually in a dorm with a roommate and common bathroom facilities, along with all the other stresses from exams, and dates for social events etc, often contribute to bowel irregularity and anxiety.
I don't know if it's possible for you to consider colonics, but if there is someone nearby offering them, and the price is within your budget, they might be able to bring some relief.
I can also tell you that others in similar situations have managed cleansing enemas in college dorm settings using an enema bag that resulted in considerable relief. If you are interested, you can followup here or e-mail me for some of their experiences and suggestions.
