I doubt you forgot everything. It's your brain tricking you. You began school with a strong knowledge of the of the things you were aware of. Now you're aware of many more areas so you feel like you learned nothing overall. Imagine a large circle A with a smaller B inside of it centered on the same point. A represents your awareness of all things computers, the set of things you know about but haven't learned yet. B represents the things you know very well, a few programming languages, some math, etc. While you've been learning, A and B are both expanding, but A is expanding faster than B. You're feeling intimidated by the things you are aware of, but don't know very well.
