I catch a cold yesterday while working, finished my shift and went home. 4 hours later I was so tired I laid down on my bed and woke up at 4am the next day, meaning I slept for 10 hours straight.

I called in sick and went back to sleep. 4 more hours.

I woke up, cooked something, ate, watched netflix and kept falling asleep. I started feeling like a person at 2 pm.

I went walking in a park for 30 minutes and went back home, started reading some epubs started having a headache and feeling tired, called in sick for a second day in a row and if tomorrow I feel like this, it's gonna be the third day in a row I feel tired and very strange, like not completely awake but not tired.

I was hoping to go to the doctor today, but I'm so tired.

I didn't feel so tired while walking those 30 minutes I mentioned. Now I wonder if walking outdoors makes people feel more awake, because the air has more oxygen than inside my bedroom and if I should open the windows to let some fresh air inside.
