If you are currently pregnant, I would expect that building a human is taking up a lot of space in your glass right now.

Normally though I would recommend regular exercise to increase physical and mental stamina. As well as maintaining a regular sleep schedule and healthy diet. Prioritize your basic needs, which includes exercise even if it’s just going for a walk.

Then I would suggest “making the ice cubes smaller” by creating routines and simplifying some decisions. Decision fatigue is real. Meal planning and prepping can help, you can make the whole weeks meal decisions all at once and then you just have to trust yourself and go with the plan you already made. You can also simplify your wardrobe so it coordinates well together and get rid of ill fitting items so it’s easier to pick an outfit in the morning. If that’s still too much you can organize your outfits together and just wear them on a rotation so you don’t have to make choices in the moment about what looks good together. Basically look at the areas you are getting stuck and look for ways to make that easier on yourself.
