Going over the edge.

I feel like a failure. I'm seriously losing it. I feel so worn out right now. I'm failing everything from math to spanish to science. I keep thinking, Lisa you can do better than this. But it's not happening. I don't think I'm trying hard enough. It's just that I don't know how? Is that possible? Not knowing how to try harder and keep pushing yourself. I don't know what I'm doing wrong. Is it because I procrastinate too much? I only procrastinate to a certain limit. Like I do my homework and study for tests. It's like even though if I study I still won't be able to pass with the mark I like. Even if I study alot I still wont be able to pass with the mark I like. I'm up to the limit I don't think I can handle school anymore. But I love learning. I love learning new languages and new idea and help think of new ideas to make the world more efficient fo living. But at the rate I'm going, I dont think I will be able to do anyone any good. For once I would like my 3.2 GPA back. Is that so much to ask for?
