Who do you turn to when you're depressed/upset?

This is just something I'm rather curious about. Who do you turn to when you're upset or depressed? Out of curiosity. Because different people thinks differently, who do you trust to listen to your problems? Also, feel free to type up a story if need be. It'd be an interesting read, for me anyways.

Here's mine.

 Spoiler

I was depressed at night, today, actually. It was around 9 PM, I told my girlfriend how I couldn't stand it anymore, the fact that I was doing completely terrible in my Math class. She sat down in front of her computer monitor until 10:30 PM just to chat with me. She asked me what was wrong, she tried to cheer me up, she said positive things about me which completely cheered me up.. She told me how she hated the fact that I'm not as "perverted" -laughs at this part- ..as usual, and that she doesn't like to see me depressed. She told me how great of a boyfriend I was, the fact that I was always with her, through thick and thin, and that she's glad to have me in her life.

She managed to cheer me up, not only that, but she wouldn't go to sleep until I cheered up and promised her that I'll go to sleep soon. She told me that no matter what, I should keep trying to do well in that horrid math class. Afterwards, she told me how much she loved me, and that I'm so adorable, lol? We said our good-nights for the day, she turned off her MSN messenger first, and she proceeded to bed.

So to sum it up, I go to my girlfriend when I'm depressed. She cheers me up all the time, I'm very glad to have her in my life. Every time I'm pissed off at her or upset at her, at certain times, I try to think of these moments.. the good moments I've had with her, and how much we've both been through.. Back when I first dated her, I had a terrible anger problem, I've managed to get over it by being with my lovely girlfriend, and I learn a lot from her. So, who do YOU turn to when you're upset?
