Is it winter?

Its in the 60s still and it was in the 70s earlier. Its a nice change... but I dont know i dont feel relaxed, not that thats unusual. But I'd been doing well at not thinking about work on the weekends despite working late nights ... today though its like if I stop doing whatever for a minute to myself all I can think of is how much work i still have to do next week and then i'm on vacation and its bothering me.. its annoying...
