We all have the right to die. Our life is in our hands. But taking steps to actually die is more complex. To me, suicide is in more forms than people think, and I'm not talking about methods.
Smokers are technically committing suicide, except much slower. These days, if someone starts smoking, they know exactly what they're getting into, and they know it's going to kill them, but they also have the power to stop. The same thing can be said for someone who kills themselves very quickly. Some ways just have become socially acceptable.
I'm not going to try and convince you that living is better than dying because 1. I have never died (obviously!), so I can't really give you an honest opinion
2. I know a lot of people won't agree with this, but to me, if you really believe that you are better off somewhere else, I'm not going to stop you. My experience with depression and suicide have helped me see that the way you feel is everything. For example:
If you have a job that you absolutely hate, then quit. Stop putting yourself through hell for a job. But if you have a family to support, and bills to pay, then you should probably figure out someother job beofre you quit the one you currently have.
If we put this into a broader scale, as in your life, its easy to say there are no other options and you've tried your best, especially when you're suicidal. What I'm trying to say is, move away from what gives you pain, and live somewhere, do something that make you feel good. And if you have honestly tried that, and you're still in pain, then I would let you go.
I know I've rambled, but thats my 2 cents on dying.
