Another parameter that I've figured out I can use to judge my mental health is the speed of time that I experience at that time. For example, just a couple of days ago - I was wondering about how fast this semester has passed by and eventually back to square one, I got back to wondering how it's got to be connected to my happiness quotient.
The title of this post is the title of a track that I used to listen to on loop back at the midst of 2020 when the uncertainity in the atmosphere just supported the gloom of the situation even more - when was the lockdown going to end and when was I going to get a chance to see her in person.
