Even though you miss it, it's good you're not able to do those little household things you enjoy so much just yet. It's important now to focus on rest, rest, rest! Your body will thank you as your system recovers from the initial shock of the surgery.
My foot, ankle and calf swelled at just about the same day post-op as yours. The only thing that helped was elevating - so try this. When you're in bed on your back, place a pillow under your knee (position it a little closer up towards your thigh, I found it uncomfortable right in the bend of my knee - felt like it might interfere with circulation) and then stack two or three pillows under your foot. It might help to "layer" a few pillows from knee to foot so that the incline increases gradually along your calf, if you need a little extra support. You'll probably need someone to arrange them so you're not bending/twisting/reaching, but use as many as necessary in whatever configuration makes you comfy - key is foot higher that knee. This helped me with the lower back strain of sleeping on my back - as well as a pulling sensation I had in my groin, and it also alleviated the swelling in my ankle/foot within a day or so. I'm 4 weeks post-op and still sleep with my foot elevated a bit, and keep it on top of a pillow on the footrest when sitting in my recliner as well.

Also remember the 'post-op blues' will hit you at some point - maybe they have already. I crashed very low at about 3 weeks, and I'm still a bit up-and-down at 5 1/2 weeks. It's all part of the process. I think feeling miserable is sometimes our bodies' way of forcing us to do nothing! It'll pass.
