When talking about work, and this week, you were so busy that you just went to work and then straight home every day, and had no time to enjoy your private life, you can explain this by applying the above suggestion.

"I haven't had any time to myself" - The phrase 'time to myself' is a way to refer to time you spend doing what you like to do for relaxation or fun. "I haven't had any time to myself" means you have spent your time on other people or responsibilities such as work or family obligations.
"I've either been at home or in the office" - If you want to express that you haven't been able to spend time doing anything other than working or being at home, this is the simplest way to say so. This expression can mean you have had "time to yourself" but only at home.

This is something that is becoming increasingly popular in the modern work culture. This is just one way to describe the fact that you only worked and slept for a week. I hope that this helps. :)
