CMV: "My Body, My Choice." Should apply to those wishing to take their own life.

Suicide is a tragic thing, don't get me wrong, and it's not to be taken lightly either. However, whenever we say "My Body, My Choice." It's always brought up in abortion debates and I myself feel like that same logic makes sense for people who wish to die but yet, stopping them is seen as heroic and correct while generally abortion arguments have a solid population on either side. (One side believing abortion is okay).

So why does this rule apply to one and not the other?

I myself have gone through a mental breakdown before and wanted to die. (I'm currently thankful for being alive and improving on my desire to do so) But I remember knowing how while it would hurt my loved ones, it's my life isn't it? I know some may say "See? You're happy you're alive!" But you could also bring up that in an abortion situation the potential child could be happy to be alive as well. (If arguing abortion is wrong, this implies it's the wrong choice) Sorry if it's hard to follow, I'm not the most talented person with words.

Basically, to one party we say "do whatever you want cause it's your life and your body" but to another we say "you're not allowed to do whatever you want because we say so."

I'm open to any ideas, I'm just stumped by myself.
