Suicide is never an easy subject, and I hesitated before responding, but I figure an opinion is an opinion, you know?
My personal belief is that there is always another way out of things. Ending your life isn't just about you. Unless you're a hermit living under a rock way out in the middle of nowhere, your suicide will affect EVERYONE around you. Don't think that you're completely alone, you're not. It's never, ever, just about ending your life. How will your suicide affect the people around you, people who love you, even if you don't know it?
What about the cleanup? Who is going to do that? I don't know if you're familiar, but there is no 'clean-up' service for crime scenes [Homicide, suicide, you name it]. So, more often than not, the family members get the happy job of cleaning everything up. This can range from cleaning blood off the floor to taking down the noose from the tree. What about them? Who are you leaving behind? How would you like your loved one to have to wade knee-deep in your blood after having just lost you...
Unfortunately, the majority of people who actually do commit suicide show very subtle signs that they're thinking about it until it's too late. The majority of people who do commit suicide are men, and they hardly show signs until you look back after they're gone and see those tiny signs. This might sound mean, but most people who attempt suicide [unless they're caught at the right moment, which rarely happens] aren't actually thinking to go through with it. If they wanted to be dead, they'd be dead. Their attempts are a cry for help, which sometimes go unheeded.
You can probably tell by now that I've lived through this, more than once in my life. It's something I'm very passionate about. So, I'm biased against it. That being said, there is always help out there if anyone is thinking of suicide.
Since that very important person in my life chose to end it, I've always lived my life to the very fullest. I will always choose to keep going, no matter how bad things get. I could be diagnosed with terminal cancer tomorrow and I'd still choose to do everything in my power to keep my life going. What that person did changed my life forever. I lost what little childhood I had and had to grow up fast. Granted, I wouldn't be who I am today without what I went through, but I'm not thanking his suicide for my wonderful life. *I* made my life wonderful in spite of things, and even now, seven years later, I'm still mad as hell at him for what he did. But that shouldn't suggest that I love him dearly and wish that he'd have chosen a different path.
I apologize if this is all over the place. It's a topic that's near and dear to my heart, and I'll say this now: If you need someone to talk to, don't hesitate to drop me a PM or an IM. I don't care who you are, I'll always have time to talk to someone who needs it.
