While writing in general has always been a passion of mine,
I mostly focused on topics on social factors, and only slightly dabbled in the sciences. For this review paper, I wished to investigate a personal curiosity of mine. What is anxiety and depression? One question I always had was, what are the symptoms that classified anxiety and depression? Are there any parameters? If I am sad, am I depressed? 

 

Thankfully, anxiety and depression, and other Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) classifications, had very distinct parameters that were usually associated with biochemical environment differences.
