I did that a couple of weeks ago. I just didn't feel motivated to do anything so I laid on the couch while my son played for essentially the whole weekend. I did basic stuff like go grocery shopping and stuff but I didn't clean or do laundry or anything. I got nervous too because that's depressed behavior for me as well but by Monday I felt better and got some cleaning done. Try not to work yourself up too much about a possible depression. Sometimes we just need some shut down time. I hope your anxiety subsides soon!
