I think people should be legally allowed to end their lives.
I cannot jump inside of peoples' heads, I don't know what it's like to be them, so it would be inappropriate of me to assume there's a magical way to make things better for them.
Yes, perhaps therapy and liver crippling quantities of drugs can help, however, I'm of a cynical disposition, so I don't really find a mountain of value in life anyway.
If you're not enjoying it... hell, it's understandable, life doesn't exactly get miraculously better.
The greater part of your life is spent slowly deteriorating and fighting to live as long as possible before you kick the bucket.
Life is not glamorous, so if someone looks at it saying "This is not worth it" I can understand and respect their decision.
