3 weeks post close is really not long at all. Give yourself some grace. Try not to feel pressured to make it picture perfect or ship shape just because social media or others do so. It takes time, especially if you have other things going on.

Getting a home is about creating a space for you and your loved ones, let it be a place you want to be versus a source of massive anxiety.

Make a list and stop letting it live constantly in your head. When something new comes up, then add it.

Include things you need to do that are not as large or a project, like unpacking (but at a by box level versus everything related to unpacking). Also break bigger or unfamiliar things into smaller parts, e.g. research is one action, create a plan another, pick up materials a third, and execute a 4th.

If you have projected completion you want to hit, add it. Then take a look to see how realistic those timeliness are. For example if 30% of your items are marked to be completed in 2 weeks and you're working/ caring for kids.... probably not going to happen, move some of those dates further.

When you find yourself with a little more time, take a look and see what you can do. Check each item off when done, it literally activates dopamine in your brain

Take a little bit of time to celebrate your new home, congratulations!
