Hi. I was reading your story and something similar happens to me. I always feel really sick in the morning and almost always have a strong stomach-ache that only finishes almost at noon. After I pass through this pain I feel exhausted, I think it is due to a loss of energy trying to hold on to the pain and my nerves so I won't do anything unless I am in the restroom. Yesterday, I read an article (http://ezinearticles.com/?IBS-and-the-Role-of-Serotonin&id=1254013), that said that it may be possible that this IBS is related to lack of serotonine, which could also explain your sad mood. Don't give up and try to get therapy because this can only make things worst. I know it is very difficult to move on but anyway, we have to try!!
