Yes, I considered/planned it twice. Once when I was 15, and had gotten in trouble for "dating" (i.e., holding hands and kissing) a "worldly" guy. I planned it all out and chickened out at the last minute. How terrible is that? Over something so little...but that's the guilt I felt because I was "bad."
The second time was when my father admitted to his sexual abuse of me. I wanted to curl up and die to make the pain go away. Luckily, my now-husband was around to pick up the shattered pieces of me.
