Third trimester hibernation (and saying NO)

Anyone else feeling an intense urge to cozy up at home and see absolutely no one late in the third trimester? I feel like I should be making plans to see folks before the baby comes, and people keep asking if I want to get something on the calendar to hang out before everything changes. When I get those texts I literally just want to cry. Like. . .honestly, I love you, but no, I don't want to make a plan. I'm tired, my body hurts, I feel like a planet, and I want to be with my husband in the last few weeks we have before it's not just us anymore. When I do make plans, I dread them. I feel so guilty but so, so tired. Can anyone relate?
