Brain fog can happen to anyone and it's not a personal failing or a sign that you're not coping. Often, it's simply your brain's way of saying it's tired, stressed or overstretched. Remind yourself that brain fog is usually temporary and it's okay to slow down, delegate tasks or ask for help when you need it. If you are concerned then you should contact your GP.
