Why is it so hard to be open when I fall in to a depressive episode?

When faced with a depressive episode, one can expect a skewed perception of reality. The part of the brain tasked with turning thoughts into words is not very well connected to the part of the brain tasked with understanding wants and needs. Adding a load of depressive thoughts and a lack of positive hormones can severely taint what little connections these two parts of the brain have. While one may believe that they're incapable of expressing their emotions correctly and concisely because of their incompetence, the actuality of the situation is much more complex. There is nothing wrong with who you are as a person when it comes to this inability or difficulty expressing emotions, wants, and needs; this is simply a scientific issue regarding the connections in your brain.
