My mind is not feeling well

I might not studying today because I am not feel well mentally. My mind is wandering off. I am thinking about school, job, going to Shreveport next week, my family and friends, my dog, and etc. My mind is racing every second. I can't focus today on my studying. Maybe I need to get some more sleep. I slept early last night but I guess that wasn't enough. My body feel tired today. I should stay in bed today. Maybe tomorrow I will feel better.
