Find it hard to agree with that, what you said is just a view of a small percent of people, there are so many reasons and some very complex.
The world does have faults, but as a whole is not a very sick place, it depends on your present state of mind, your failures or those who have failed you may be responsible for making you have this bleak outlook.
Maybe some counselling can help you doug, get things back on the right track, life is too short to be miserable and believe it or not with effort, even meds it can be not so bad, I know I've been down that road, contemplating suicide myself, with help I have changed my outlook, you have that ability too.
Please take care,
