Experiencing lows in life makes one confused, loose self confidence and raises the level of uncertainty & insecurity in mind. The traumatic imagination about where current events are headed to, how bad is it going to get & how it will affect you makes one nervous and feel scared. One starts questioning own credibility and is engulfed by self depreciating emotions.  It is the onset of depression. Consult a professional who helps one release the racing thoughts that interfere with one’s resolve to succeed, are judgmental, causes confusion, doubt self, feel ashamed & critical of failures and restructure the emotions to deal with internal conflict and maintain good mental health.
