Trouble putting my thoughts together

I am having daily problems with my cognition. I wonder if this decline is related to me working too much. I'm really trying to balance way too much! I wonder if my thoughts would be clearer if I only worked one job. I need to find a way to pay my bills, live on my own, but be able to do that working only one job. I also coach a youth bowling league every Saturday morning, then I work an eight-hour shift at a retail store. I work six days a week, thirty-two and a half hours a week at an elementary school and sixteen hours a week at a retail store. My only day off is Sunday!
