For the last 2 months or so I've been sick with IBS like symptoms that have ranged from moderate to severe, but it doesn't seem to be at all related to what I eat. My gut just feels messed up all the time, whether it's with diarrhea or constipation, and I feel like I have a lump in my throat. This all came on very suddenly and isn't going away, and I've had all of the appropriate medical testing (which shows me to be physically healthy). So I'm beginning to wonder if these physical symptoms are related to some sort of anxiety. I guess you could say I'm kind of a nervous person, I tend to worry a lot about things I have no control over (sometimes for no reason I'll get a terrible feeling that something bad might happen to a friend or loved one, and i have bad nightmares about this). But all my physical problems started at a time in my life when I was feeling quite happy and at ease (though I'd gone through a particularly stressful period a few months before). Does this sound like it still may be some type of anxiety, even though it wasn't caused by an immediate stressor? If so, what do I do about this? I am totally clueless and scared because I don't understand what is happening to me and nobody seems to be able to give me any answers. I've never so awful for so long before, and any advice anyone could give me would really be appreciated.
