This is how depression workds. It tells you all these things and you're a failure. But it's probably the depression talking. Just because you only got for so far with things doesn't mean you failed at them.

I can sai I failed as a daughter, too. But, you know what? I didn't. It was my dad who failed me. I was just a kid and he expected me to be an adult right from the start. He set impossible goals for me to reach, and when I didn't reach them he told me I was a failure. And he continued doing that to me until now when I am done with him because I am not going to be his joke any more.

So, sometimes you have to look at things in a new light.
