The brain is the most complicated organ in the body. Just like any other organ, it can cease to function properly. My brain doesn't make enough neurotransmitters and as a result I have depression which is complicated by PTSD. I take daily meds and see a therapist as needed.

I am grateful for the meds. Fifty years ago the treatment for depression was ECT and/or a long rest in a sanatorium. Suicide was a "treatment", in my family......3 members killed themselves bkz they didn't have the opportunity for meds. Self medicating with alcohol or illicit drugs is also a treatment of choice.

If I look at diabetes in the same light as mental illness, there are similarities. If my pancreas ceases to produce insulin, I get sick. Chances are a doc will give me medication. To enhance the meds, I am sure I would have to watch my diet and exercise. I would have to follow this plan for the rest of my life if I chose to be as healthy as possible.

Your last question, " Does it ever go away?" Yes. If your depression is situational or reactive, it can be resovled. The same can happen with anxiety disorders.
