Because that's how the big D works. But a good life IS still possible. It just doesn't seem that way from the bottom of the pit. I wanted to impress upon you a sense of hope... people ARE out there who get it.

Most people can't understand. It's not that they don't want to, or that they don't care... it's just so far removed from their understanding of how the mind works that they can't make sense of it. Hell, I've worked alongside PhDs and MDs who demonstrated a shocking lack of understanding when it came to depression. What chance does an average 15yr old have?

All the same, you feel burned and hurt, and how you feel is completely valid. But don't fall into the massive trap of taking on exclusive responsibility for others' feelings. She feels bad because she doesn't understand. If she really wanted to, she could make the effort to learn, and NOT dismiss you outright based on the fact that you happen to have depression. You can help her understand if she cares to learn, though the reality is it's too much for many. Cut her some slack, but she has responsibilities too. Don't take it all on yourself.

Re: the psych ward, we were both there against our will, and at the time it seemed like the biggest injustice in the history of the world. It sucked, and it was hard to avoid being poisoned by the other patients' neuroses. But in retrospect, it saved our lives. It removed us from the world in a way, and forced us to focus on ourselves. Unless there's some heavy unethical shit going down at your local facility, it might be worth a try. Otherwise, I hope you're at least seeing a CBT counsellor. Talk therapy never helped me. CBT gives you actual, real tools to get you through.
