There's no doubt that victims of abuse suffer from depression. Some go through short bouts of it over years of their lives. Some go through extended periods of it, months at a time. Some don't live through it at all. They take their lives because the pain is too great.
Depression is devastating. It has broken families and destroyed dreams. Depression steals the life out of people and renders them emotionally helpless. The problem is that it's so common that most people take it for granted.
I've battled depression nearly all my life. I can remember it hitting me as young as five. Now, I'm 32 and still have to be diligent over my emotions just to keep it from coming back. I don't personally medicate, but that is because I don't believe it worked for me when I did as a young adult. I can't say what is right for you, but I remember standing in front of the mirror one morning and not recognizing myself. My hair had fallen out and gotten thin. My face was thin. My eyes looked like they were budging. I looked sick and lost, kind of like a zombie. I got angry and threw the pills away. I was 20 years old then, and for the last 12 years, I've battled this the hard way - one day at a time. It hasn't been easy, but it has been rewarding because I'm not telling about something I've read. I'm telling people about what I've lived through.
Depression is a thief. The same way you'd watch a thief that visited your house, you must watch for signs of depression and learn how to arrest it early on.
