You could be suffering from an undiagnosed mold illness.
Things didn't used to be so difficult to accomplish. It didn't used to be so hard to make it through a day at work or school. Now you find it almost impossible to get through simple things like reading, or a load of laundry. You are so tired all of the time. Doctors can't seem to pinpoint the problem. You wonder if the rest of your life will be like this?
