Chris Cornell was objectively successful. A super sexy, rich rock star. Depression isn't about what's going on in your life, it's not about what you don't have. In fact, in my experience the more successful I became and the more boxes I checked, the worse my depression seemed because it became clear that I couldn't do anything externally to fix it. No amount of money or family love or success was going to fix it. The disparity between a good external situation and a shitty internal landscape can make it worse. 

My point is, if you're thinking "I'm ugly and broke and friendless,  I'll kill myself" that's not an accurate picture of why you want to leave this world. Your depression is LYING TO YOU. Don't believe the voice that tells you there isn't any hope. It's bullshit. All you have to do right now is not die. You only lose this game when you quit. So DO NOT QUIT. 

I spent a decade of my life fantasizing about suicide, wishing I wasn't here, and I'm mostly happy now. I promise you there is hope. Hang on please!!!
