I feel so alone. Depression is way worse when you feel like nobody in your life will ever understand what you're really going through and how you're really feeling.

A few months after I realized that I was slipping again I got back into counseling and started opening up to friends more. It wasn't enough. I felt like there was no way out no matter what I did. Well after months of nothing but pain and hopelessness I snapped and ran away just trying to get away from it all. I thought that if I just got away then everything would be better. My depression told me that there would never be any way out, and so I ran.
After five hours of driving I sat behind a rest stop sobbing and listening to the voice that told me nobody knew or even cared where I was. But it was at that rest stop that I heard another voice. And for the first time all day, I listened to the voice telling me to go and get help.
So I turned around and drove another five hours back to check into the hospital for the third time over the past four years. They told me that I'd had a major depressive episode and they diagnosed me with major depressive disorder. The doc told me that this would be a lifelong journey. AHHhhhhhhh!
Two weeks and a medication change later I come home, no longer feeling suicidal, but still just really depressed. Insurance stops paying for the hospital two days after you stop being actively suicidal.
I hate this. I was doing great for the past three years, but then this. The last thing I want to do is drag my family through the mud again.

Can ANYONE relate?? At times I feel so alone, like I'm the only one in the world going through this. Is it considered totally insane to just leave one day and go for an unplanned ten hour drive?
