Eighteen? That's just high school. My plan was and would still be going to college. If you're referring to the summer in between high school and freshmen year of college, I might just try to have fun and enjoy that interim. Actually, I forget what I did that summer. I had just returned from a trip to China PRC at that time (slightly hypomanic). The summer flew by, quickly. I think I was also at least hypomanic during my first semester at college. I think I was better, mental health-wise, during the second, if I recall correctly.

If you attended college (undergrad, grad, other) which semester gave you the most trouble, and why?
