Any multi-step process drains my mental energy, even basic ones like getting dressed. It shouldn't take me 20 minutes just to change clothes, but there are days I need to regroup and refocus between each step.
I had an idea when reading this and it may be helpful or it may not. It may require too much work to start it but I wanted to mention it in case you do find it useful.
Some people have success using a minimalist wardrobe. For some, this means having a limited number of clothes with preplanned outfits. Others buy multiples of items and wear the same thing every day. For example, they own four pairs of jeans and seven black T-shirts to wear every day. (Or another work appropriate outfit.) They keep it simple for ease of decisions.
I cannot remember where I read this or if it has research to back it up, but some people say you have a limited number of decision making abilities per day. Each time you have to make a decision, you use up some of your limited capacity to make those decisions. One idea behind the minimalist wardrobe is to eliminate some of the nonessential decisions in the morning to “save” the decision muscle for the more important things.
Now, planning a minimalist wardrobe and or/buying a new wardrobe might be far too much to take on right now. But you might try the idea behind it of eliminating any nonessential decisions. As someone else said, offload anything you can to make it easier on yourself.
If it works with your finances, try one of those meal plans where they send you the food precooked (or if you enjoy cooking, perhaps the meal kits) so you don’t have to prepare or think about meals. Just pop it in the microwave. Or frozen dinners.
The easier you can make these tasks, the better. Even a can of soup requires a couple steps that can be eliminated by a frozen dinner. You want to make things as easy to accomplish as possible. The more you can accomplish, the more likely you are to continue to work towards accomplishing things.
I hope this helps. Please keep us updated on how you are doing.
