I am doing my assignment on depression because when I learned what it was I figured out it is what I went through. Depression is a severe despondency and dejection, typically felt over a period of time and accompanied by feelings of hopelessness and inadequacy. Its hard to go through a depression stage whether its from losing a loved one or losing a long term friend to death but all in all if you know some one is going through depression, help them.
For everyone who goes through depression, like I did, before it gets really bad I highly suggest you go to counseling or get a prescription to get depression medication. I know someone who had a major break-up and went through a small depression and she went and got help and got depression medication and it waded over time and now she's happy again.
