i don't think bravery has anything to do with it, suicide is a mal-adaptive behaviour to say the least. You sound really depressed, please try and talk to some one, sometimes things that seem impossible can be worked out.
Do some meth, it will totally change your outlook on life and you will be more out going. One of three things will happen, you will end up dead which is what you want now, you will end up in the garbage bin (jails or institutions) or you will become a recovering addict and possibly contribute something to this world (slim chance of recovery). Choice is yours, stop whining and bitching. Look towards the good in life. And no.... don't turn to drugs. If you put all the options I left you together, your chances are not good. Be happy, talk to people. I mean real people, not hip forum virtual world people. Look for something somebody has that you want, hang out with them and strive for the best, and I'm not talking about their wives...
There's always some bright light at the end of the tunnel...You just haven't gotten far enough to see it yet. I suggest you talk to someone who can help you, depression with suicidal thoughts isn't something you should keep bottled up inside.
There is always secret option C. Meth won't really help your depression more than likely it well add to it. Instead trying some pot or perhaps a psychedelic. Trust me man I have been there two years later however I'm still here that has to amount for something. I'm not saying that the drugs where the entire reason, they did however change my outlook on life. My two cents.
