Hi. It isn't easy to work in such a distressful environment. Taking a leave for a few days is a temporary fix. I would suggest you to see a psychologist and work on your symptoms. She or he will be able to guide you better and give you strength to manage or even overcome the situation at work. Life is a beautiful gift and giving up because of whatever issue is not the solution to that issue. When we are in such a situation we tend to see the world as a horrible place and everything seems to be negative. But that's not the case always and you'll be able to see that with the help of the psychologist. Hope this helps.

Feeling low, having crying spells, sleep and appetite disturbances, and difficulty in concentration and attention are some of the signs of Depression. Consult a Psychiatrist for a detailed assessment. It is likely with medication and counseling the symptoms will improve. If you are feeling suicidal or hopeless consult a Psychiatrist immediately.
