I'm going lie to my family and pretend to go to work all this week
I don't know how that will work. Aren't you required to go to work?
I have to go or I'll get fired.
It is understandable to want to take some time off.   You should be honest about when you do and do not work in order to avoid losing credibility.
I can just get another job.
What do you think will happen when you need references to get the new job? It's important that you fulfill your duties at work, so they'll be able to vouch for what kind of worker you are. If you don't like your job you should give them notice before you stop showing up.
