I'm against it. I think if it were to become more available, depressed people would immediately turn to it, and as a result, die from it. I know sometimes people are incurably depressed, but I've been depressed for a long period of time before (3-4 months), and I'm not even gonna lie, I thought about killing myself. Eventually, things turned around and all thoughts of suicide left and haven't come back.
If I had been in a position where I could go to a doctor to die, and I wasn't a minor (I'm sure kids wouldn't be able to just apply for termination), I probably would have considered Euthanasia as a means of getting out of depression, and out of life. If that would have been the way things worked out (me dying with medical assistance), I wouldn't be here today posting on this forum. I wouldn't be around in a few years when hopefully I'll be in college, advancing my education. I wouldn't be around 10-15 years from now, when hopefully I'll be a husband and father.
I'm not sure depressed/sick people are well enough mentally to make decisions like that, and for that reason I say no to Euthanasia. I think it's best for everyone if it's unavailable.
