Suicide ?

One afternoon I climbed up to our rooftop and sat on the dusty roof of our house and I always liked the feeling up there when you lie down in the roof  and see the great blue sky… the great blue sky alone (unlike most of the times when you look at the sky but other things like lamp post or building is there). Well this afternoon I walked in the edge of our rooftop and I could see people busy and cars passing by what would happen to me if I jumped from the building. “No one has the right to take your own life cause it is not your own… the life that we live is only borrowed from our Lord” Ofcourse this answer came in split seconds (I guess that’s what happen if you go to a Catholic school in the 1st half of your life and in a Christian school in the second half cause they do have the same answer for this question) and I suddenly taught of this question “What are the teachings of other religions about suicide”. Since I’m a chinese I have other friends who’s family’s belief is Buddhism and I asked one of my friends if she knew the answer but shockingly she didn’t know it and she said she doesn’t really know Buddhism well, It’s weird how can someone like her declare herself a buddhist, she even had this bracelet that has something to do with being a buddhist and doesn’t know what she believes in. Anyway here is the question “How does Buddhism view suicide?” I’m interested in Buddhism but I would be glad to know diff. religions’s view in this matter. Many thanks for the answers ^^
