Oh Yayme,
I would like to welcome you to PC.

Wow, what a stupid doctor. I hope you never go back to him.
He should have never said that to you.
Yes, you are right. It is in our head. Our brain to be exact. When we have depression, it's because we are chemically imbalanced.
I, too have fought depression since I was 14. I am now 52. I have had severe depression for most of my life. I am now on two different ant-depressants and I can't tell you what a difference it makes.
Before, I would turn off the phone, close the curtains and lock the doors. I stayed in bed most of the time. I didn't want to see anyone or talk to anyone. Not even my family.
Now, I am so much better. I have hope again.
I do hope that you continue with your anti-depressants and remember, that sometimes, they don't work or quit working and you have to try a different one. So, if you start taking them again and don't feel a change in your outlook, then it's time for a change.
I wish you all the best and you can pm me anytime.
I do understand how you feel.
Hugs,
Boopers
