Does your bf know your situation? If so, maybe he/she would be okay with getting take-out and a movie at home.

Others usually mean well, but when I'm feeling that way, it's more of a burden to reach their expectations. If you can't bring yourself to go out, don't feel guilty. Just let them know that you appreciate their thoughtfulness and effort, but you just aren't up to it. It makes me feel anxious and ashamed, like I'm admiting my weakness, but in the long run I'm better off (otherwise, I'm forced to cut those people out of my life). Be honest. The truth hurts... but forcing a fake smile... can hurt more.
