Hello - I Am Experiencing A Tremendous Amount Of Stress

Hello - I am experiencing a tremendous amount of stress with family and financial issues and it has been going on for a year. I am female, 68 years old and in excellent health, but lately, every now and then. not often, I am experiencing confusion. Today for example, I wanted to apply oil to my skin after my shower and was clear in thought about what I wanted to do, but had difficulty picking up the oil and doing it. Eventfully I took the oil into another room and successfully applied it there. I was able to problem solve but had trouble with the task. I figured it was a result of the stress, but how can I be sure? Thank you.
