to tired to start nursery! where do I start

Ugh I'm 21 weeks and I want to start our baby's nursery, but I'm always so tired plus I go to school 5 days a week, and l honestly really want to be able to just get up and do it but it's so hard, plus I always have trouble sleeping 😒 anyways we have sooo much work to do idk where to start, we need to clean out the closet in there, fix the holes in the wall with drywall, then pain it, plus there's a couch and a queen size bed in there right now so we need to move those out of there, like ugh!!! Idk where to start, we don't have drywall or paint yet either. What should I do
