Help?

I was trying to find something online to help me feel better, but most things really annoy me right now. I read some blogs and it just made me cringe. People write how they fight with depression and how they've discovered how strong they actually are and how it's made them the person they are.
Really?!
 I never feel this way. I can imagine this attitude being good for them, but I never feel this way. Strong? Right now I cry because I need to do the dishes. I've been crying the whole day at nothing. Literally nothing. I feel vulnerable and I want to cry. I don't even seem to have any thoughts that trigger it, just this feeling of some pain inside. It's overwhelming.
And when I have these days I hate my depression and anxiety. I hate myself for having them. I don't feel like this is me. The real me is buried under all the anxiety, fears and tears. It doesn't show at all.
And all the optimism! I know I can get through this, they say. I know I'll get through this too, but it doesn't make this any easier. It actually makes me feel worse. I know it'll pass but then I know it'll happen again and again. I'm not overcoming it I'm just waiting it out. That doesn't feel like strength to me it feels like helplessness.
