I understand your topic and want to throw in my 2 cents worth. I agree with you. Having a physical ailment on top of a mental illness would be difficult, depending on the form of mental illness; could cause different responses to the physical illness. In my experience, I tend to ignore physical symptoms until they are overwhelming; because i place little value on self. However another person with depression might be a bit of a hypochondriac, running to the dr to cure every phantom pain/ distress. Many of us do have physical ailments such as IBS, migraines and other issues. We either choose to give in to them and seek our beds/rest/solitude; or we choose to muscle our way through the discomfort until it becomes unbearable. after all, we are already in pain, thanks to our own mind working against us; what is a little more pain? I hope my response makes sense
