I'm already in a terrible position, confused and feeling hopeless, and then I get my last grade back today, a B+ in Philosophy, a class that was suppose to be easy to get an A in, according to his past grade distributions. I'm not going to be on Dean's list this semester for the first time. Again, I'm trying to rebuild my life here, trying to fix all the wrongs of my past, and then this happens. The one accomplish I had is now gone. What exactly am I suppose to do? How do I do this... with nothing?

Nothing at all.
If this isn't rock bottom I don't know what is.
