Foster's has definitely helped me when I feel depressed. It always makes me laugh, and just turning the show on fills me with comfort. The characters are like friends and when I'm watching them I don't feel so alone and scared when things aren't going so well. And my Bloo plushie is my favorite thing to hug when I'm down. He sure helped me out a lot last month.
If you want a weirder story, Foster's led me to look into getting to know the voice actors, particularly Sean, which led me to his MySpace page, on which I saw the words to the song "Hey There Delilah" by the Plain White Tees, which got me interested in that group, and when their newer song "One, Two, Three, Four" came out, an old friend of mine said she also loves that song, which led us to talking more and so now we're getting re-acquainted! So, I kind of gained a friend!
Of course I gained friends here, too.
