I'll be applying to grad school in the fall. I checked out that link you posted, and yeah I guess I'm not alone in the post-graduation depression. I'm trying to get excited about grad school, but can't help but get intimidated whenever I think about it. I am leaning towards science and technology studies for PhD, but keep getting thoughts of like what am I even going to do with that? I'm still applying though. For now I am just going to keep at it with those internships. I've realized I need to stop envying other people's success, such as my professor's and just make my own success. There is nothing attractive about moping around all day feeling self-pity. I'm going to start building my own future, get that cool research job, get my own ivy league degree, and be my own person. I'm getting stoked just thinking about it. Why fixate on someone else when you can focus on building yourself? For this summer though I have no idea, it's basically to late to apply for anything so I don't know. I think I'll start going to the gym though, burn out some stress. That sounds healthy.
