I Want To Know If I'm Depressed Or Not. I

I want to know if I'm depressed or not. I felt down for about a year and I'm always tired. I get migraines a lot. I just feel hopeless a lot. And I get pains in my chest and it hard to breath sometimes. I feel out of control too. I don't know if thats anxiety. I have done research and my symptoms seem to match what being severely depressed means.
