The people who are employed in my department don't show up. But I do, because I have no other source of income. I have to work to support myself. Right now I am doing my job and the work of two other people (who have a variety of excuses for not showing up; apparently the company is cool with them taking off days and days at a time), plus babysitting my boss, who apparently has nothing to do but harass me. I know just want you mean about not wanting to go to work. Work sucks. When you do go to work, why not try being honest about how you feel? There is no need to "put on a happy face." Unless you are modeling cosmetics or teeth whitening products, I see no reason why you must smile or pretend you're happy to be there. It might be they don't understand where you work because you haven't told them.
