Perpetual Failure

It seems as though no matter what I do, things never seem to go right for me. I am a week into an online class, Theatre History I, and I just dropped it. I've never dropped a class before, and of course I was a day late to get my money back. The class was $298, and the books cost over $120, which include a ProCopy book (nonreturnable), and a CDRom (also nonreturnable). Lord knows if I will be physically taking this class in the future, and I don't know if I'll even get my full refund if I return the books now. Because I dropped this class -which seemed ridiculously difficult even for a physical class, and seemed so to Joanna who has taken hard stuff before- I will have to stay for another semester, and will (again, hopefully) be graduating in May with Joanna. It has taken me eight years to get a stupid BA degree. It shouldn't have been that hard. Joanna said that it is different for me, since I'm working to put myself through school and all, but I just feel like the worst failure at everything I do. All of my friends have long since graduated, and Joanna's friends are graduating in the Spring. I don't know what I want to do with my glorified piece of paper when I get it, I don't even know that I want to teach. But I know that there is a desperate need for teachers. I don't want to feel guilted into it though, simply because they need teachers. But what else would I do? I don't even know that I could teach. I am not a good public speaker; I'm downright awful at it. I don't have good organizational skills, and I need someone above me constantly telling me what to do and when to do it.

I think I'm making up for not posting here in over a month by such a long post now. Any thoughts? Comments? I'm open to suggestions. Help!

Edited to add: Looking at my last post, "wouldn't it suck if I had to stay another semester because of one class", I think I jinxed myself. Figures. . .
