"Defeated in the game of life" sounds familiar.
Well, you say you achieved nothing, you know it so probably you are right. However, it likely happened for a variety of reasons, not including your worthlessness. Seems to me that you life so far was an effective selfloath factory. However, loathing oneself doesn't mean to be loathsome. You have a heavy burden, not impossible to drop.
I'm not going to teach you anything, I'm a time wasting, self reproaching lazy axx. But I would bet my last buck you are a better person than you think. A person with that deep insight can't be worthless.

Bye, good luck
