It is your mind fooling you. Your face doesn't show emotion with flat affect. This is something that you can't help and when the cycle of depression changes so does your flat affect I am so glad that you are getting the help that you need. Feel better soon!
The Time of the Harvest Moon. A harvest moon occurs at a specific time of the year. The moon officially turns full when it reaches the spot opposite to the sun. The harvest moon happens on 13:59 Greenwich time on the Saturday nearest to the fall equinox, which is September 23rd.
The Moon Festival, also known as the Mid-Autumn Festival or the Lantern Festival, takes place each year on the fifteenth day of the eighth lunar month. This is the date of the Autumn Equinox, when the moon is at its farthest point from the earth and hence appears bright and completely round. Traditionally the Moon Festival marks the end of the summer harvest. To the farmers of China, the festival is a celebration of thankfulness for heaven's bounty.
