My Life is Not a Myth
Friday, August 29th, 2008There are many terrible things that people say to those with depression. Most of them are rooted in myth. Misunderstandings abound, outweighing real knowledge when it comes to correctly understanding the illness.Â
Let’s look at the worst. Readers of this blog have shared some of the very cruel things that have been said to them:
- All you need is a gun and some time alone.
- You must not be living right.
- Yeah, I know how you feel, but that’s nothing…
- You just need to wake up in the morning and decide, ‘I’m going to be happy today!’
- And you don’t even work – you have NO excuse not to have a clean house!
- My boss said to me, ‘Sounds like a personal problem. Deal with it.’
- She thinks she’s going to live forever and has time to be depressed.
- It’s a matter of MIND OVER MATTER: If you DON’T MIND, it DON’T MATTER!
- If you’d just stop thinking like a victim, you’d get over this. You control your life! Act like it!
- At least you have your health!
- Put your big girl panties on and deal with it.
These are real things said to real people.
Those speaking the words don’t recognize depression at work or they lack understanding of its nature. Or that it is a real illness. And if it’s not real, then there is no treatment. If it’s not there, then the “sufferer†is someone who just can’t deal with the stresses of life that we all face. If it’s not real, it will go away when the person learns to smile and pick themselves up.
In the words of one reader:
“The problem with depression is no one can see the wheelchair or the crutches. If they could, they’d be more careful about what they say.â€
There are other myths floating around:
Only women get depression. It’s a normal part of aging. Kids can’t get it. It only happens after something bad. Antidepressants change your personality. Talking about it makes it worse. It’s a normal part of life. It will go away on its own. You can snap out of it. It’s all in your head. You choose to be depressed. It means you’re weak. It’s a character flaw. You can psych yourself out of it.
How do we respond? We must start with education.
FACT: Depression is a serious medical condition. Most people get better with help.Â

Thursday, August 28th, 2008Triggers of Depression
Thursday, August 28th, 2008
by Susan
My husband and I spent four days at the Intensive Care Unit of the hospital with his mother who is 94 years of age. She is out of the hospital now and will be returning to the hospital soon for a procedure on her back. The many hours we spent in the ICU and adjoining waiting room were very similar to times when I was there for my own mother and for one of my sisters.
Needless to say, I believe the events of the past week have triggered some depressive feelings for me. My mother passed away in 1999. She was in the hospital for 10 days as a result of a fall due to the unsteadiness she suffered with Alzheimer’s Disease. All of my sisters, as well as my brother visited and spent time together. We all rallied together again a few years later when one of my sisters spent 10 days in the ICU on life support.
I believe significant events such as loss of a loved one and life threatening illness of a loved one can trigger depression. I also believe similar events can re-trigger those same feelings of depression, fear and anxiety.
There are so many events in our lives that are possible triggers of depression. Job loss, financial problems, arguments with loved ones, death, illness and many many more. Some of us may be depressed due to genetics and chemical imbalance but these triggering events increase our levels of depression, sometimes to the point of immobilizing us for a short period of time. If you find yourself unable to function somewhat normally for you, get professional help as well as help from family members.
Here is an interesting site that lists many of the triggers of depression “Causes of Depression: Possible Triggers of Depression?”
