I don't think you're really negative. I mean you're dealing with MAJOR life choices here! Plus it's never easy being apart from your friends and bf, which make up a big part of a person's support system. It's natural to feel stressed and down about it. I feel I've been in a similar situation for the last six years, since I graduated from college. After always having a plan or knowing what I wanted to do, I don't know what I want to do with my life! I feel as though the IBS has changed me significantly--not in a bad way. I just consider things more carefully and I realize that life's too short to be doing something that I don't want to do or like to do. I guess, at least I know what I don't like!
To me, you sound like a very thoughtful and intelligent person. I think it's great that you're posting here and sharing your story. I believe this diet and stress management really make a difference; it's especially helpful at keeping you stable during those times that life gets to be overwhelming.
Let me know if there's anything else I can do to help.
