How to I tell my wife I want to separate?

We've been married for 8 years and I'm at the end of my rope. We both have strong convictions against divorce, but I just can't stay with her any longer. I have depression, and she makes it worse, so from a purely mental standpoint it's not healthy for me to stay with her. The biggest problem is that I really can't afford to move out, and even if I could, I have a very real fear of being alone. Not telling her I want to separate is a huge burden to carry, but I'm not sure how to tell her, or if it's even a good idea at this point.
