Failing at Life

Today, after being completely stumped by a fifth grade math problem, I got to thinking about how often I fail at things. I know that everyone does badly at different things, they make mistakes or they don't do as well as they hope to on something but does everyone fail at most things in their life? In my opinion no, they don't, which leads me to the question as to why do I? It seems like every life goal or major plan I decide to do, I fail at, miserably. Example: Get a guy I'm interested in to take me to a formal dance (in highschool or college). Fail. Find a highschool boyfriend. Fail. Travel abroad for more than two weeks. Fail. Find a college boyfriend. Fail. Get a good GPA. Fail. Graduate. Pass(hopefully!). I feel like I need to change practically everything about myself to make me more successful in the things that I want. Within the next couple of months I'll find out if I pass or fail the next major life goal...getting a job. If I don't, I think I'll be unbelievably devasted. What will the point of my life be? Almost the only thing I actually enjoy is being in the classroom and if I don't have that then what do I have? Not much. I'll just be stuck at home, hating every moment of my life, praying that I'll be able to get out soon. It makes me depressed, just thinking about it.
