With the options that you describe below, it's really inconceivable to me that you're infatuated with suicide. Sounds like you have decent parents (Unless I missed something). Going away to college on scholarship, learning new things, you even know what you want to do (a physician's assistant).
If I may talk directly for a moment, because I feel it's what you need, what is this all about? Do you understand that when they cremate you or put you in the ground there will be some pain and tears from some and some horrible agony for others, but in the end, after some time, life will go on? You will be the one that killed himself/herself forever, whenever your name comes up. Is this what you want?
One of my dearest friends in the world blew the back of his head off last Monday and no one saw it coming. In front of his wife. I talked with him two days before. If he knew the hurt and devastation he's left behind he would've never done it. Six and ten-year-old kids. Best and most gentle father ever. One thing I know is that he wasn't infatuated nor played with the idea of dying. When he decided he was done living, he made sure he succeeded. Now, everytime I think of my dear and close friend since I was 13, I think of how he killed himself and how me and his three closest friends had to clean the blood off of his son's walls.
Please give up this foolishness and start living. There is so much to live for. A sunny day is worth waking up to. And so is the gloomiest. My aunt died of cancer just 2 months ago and she fought like a warrior, battling, fighting, and scratching for every breath right up to her last. She's now in Heaven with God -- the God she loved so much.
