Not Laid back

So I always thought I was a laid back person. In the past week it has been brought to my attention that I am in fact not laid back. I am one of those people who has to do things right now, which often leads to awkward sleeping patterns. Since I started grad school last week, I have been working like crazy on assignments that are due in two weeks as well as ones that are due in a month and a half. My friend said she would not consider me lasid back in fact she says I am quite the opposite. So tonight I asked my mom if she considered me laid back and she also informed me that I am not. I am supposedly hyper and very crazy about doing things the minute I recieve them. Oh well, any other words that descirbe a non-laid back person?
