Sharon I believe there are several reasons those of us without our colons can be and are depressed. I've been in weekly therapy for 2 years.
I was on a lower dose antidepressant before the surgeries. I was put on this when I was diagnosed with fibromyalgia. It is the first thing they did when I was diagnosed with it. I was depressed before the surgeries too because I was so sick. My first surgery was around 3 years ago.
There are several good books and articles about the mind and gut connection. There are chemicals produced in the colon that are used in the brain that affect depression.
We can become depressed by the situation we are in, especially when we have no control over it. When an illness becomes chronic it adds to the depression. It is not something that you can will yourself out of. You can not just decide not to be depressed. It can be situational but it can be chemical too and it can be situational and chemical both.
I'm diagnosed as having major depressive disorder. My Internist changed my medications recently and had me coming in to see her every 2 weeks to monitor the transition. I see a therapist too.
You can inherit depression problems, you can develop depression and you can inherit and develop depression. Whatever happened, if you are suffering it is important to recognize you are depressed and receive treatment. That can be therapy, medication or both.
It's not just our medical problems that can be causing depression, personal relationships and other life problems add to depression as well.

(The way I describe my depression.)
