Depression has nothing to do with being happy. It is a physiological change in the brain from too much of anything. Excessive excitement over a sustained period can lead to depression. Think of it as similar to the crash we suffer from too much stimulation. The brain becomes overwhelmed with the positive or negative stress. Over an extended period, the neuro-chemical processes get tired and start getting overwhelmed with the toxic byproducts of the stress.

It is not a matter of character or lack of character, personal strength or any such idea as many people think, etc.

My only suggestion is to seek help from a medical professional, not just any doctor, but one with experience with depression and concussion.

I routinely suffered bouts of depression after my concussions, especially in my younger years. My heart goes out to you. I know how miserable they can be. I have suffered a variety of different types of depression. I have had the "stinkin' thinkin', I want to die depression."

I have also suffered the zombie like, vacant person and confused mind depression. This was when I finally found treatment. The psychiatrist gave me B-12 shots and got me onto good vitamin and supplement nutrition and I recovered in 8 weeks.

I have also had adverse reactions to meds that put me into a deep, dreadful depression within 24 hours of starting the new med.

So, please, seek out some professional help. You will be glad you did.

My best to you and Happy Thanksgiving.
