Why me?

Finally got to have a little sit down to plan out my work to try and graduate. And, of course, I got the you need to work more/harder. That I need to be in the lab earlier. Well, sorry but sometimes early in the morning it is freak out time. I just kinda wig out, I have never, ever claimed to be a morning person.
But everyone else gets into work around 10am. And they leave at 5. With a one hour lunch break.
I get in, on a bad day, around 11. I leave around 6. And I am usually too stressed to eat lunch.
So why am I expected to work 10 hour days? I mean....no one else does.
I just wish I could explain that working 10 hour days is going to make things worse, not better?
