Depends.
Could I survive? Yes quite easily.
I have a fairly comfortable life in an external sense. I have a good education, I have money, I am financially independent, I have my own place to live in a safe area, I'm physically healthy. I have a lot of things people wish they had and I am grateful for that. It's the only positive thing I can say about my life.
However I'm a broken person on the inside, I know without a shadow of a doubt that depression has completely consumed me and I know that I'll never escape that depression living a "normal" white collar middle class life.
I know I only have two options, I either have to make a radical change in my life such as moving to live in a different country that is very different from the US or I'm going to at some point kill myself.
