Let's list off all the, "no's," shall I?

I have no... job, place of my own (potentially facing homelessness), friends, love life (and certainly no way of seeing how anyone would want to be with someone that doesn't have the first two things on this list), hope, momentum, nothing to offer except disappointment and failure, contributions to society, and really anything of note that makes a human being worthwhile. 

Now that I've lost my dog, I don't see what else I have to live for. I'm not suicidal, but incredibly lost and purposeless and no matter how I try to change that it never gets me anywhere. Like the title says, I'm just a giant waste of space and loser. I don't know what to do with myself anymore.
