Welcome to HealingWell and the Depression forum. I am glad you found us.
Your history is long and has many twists so your question is difficult. First of all I would like to suggest that you make an appointment to see your physician to obtain a medical screening exam as you have physical issues going on with your IBS and also please tell your Doc everything you have told us.
We are not professionals so to diagnosis you is out of our realm. Could you have depression, yes but you could also have other issues.
You may need medications or some tests and it is important to get your physician involved. We are here to support you and share our own experiences with you but each person is different.
Have you talked with your spouse, I know it is difficult when people don't understand but I am sure she supports you and would want you to be feeling better?
Again a warm welcome and keep posting.
