Lockdown Syndrome 

..... the feeling of depression and sadness because there is a mandatory "stay at home" mandate from the government. You cannot do what you would normally do in a normal day because you are not to leave your home, the restaurants are closed for dine-in and social gatherings are prohibited. This was brought on by the COVID-19 pandemic at the end of 2019 and most of 2020. Coined by Edward Veneracion on March 27, 2020, California, USA.

I think I have the "Lockdown Syndrome" , because I am feeling depressed because I cannot go out of my house and do the normal things I like to do nor can I socialize with my friends...
