The onset of fatigue coincides with mid-day most often. Your body discharges your brain's natural sleep chemical, melatonin, telling your body it's time to go to hit the hay between 2 and 4 in the afternoon. Michael J. Breus, PhD, a sleep expert, explains that the tiredness or fatigue you feel in the middle of the day is just like the tiredness you feel before bedtime at night.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
