I have the same feelings when I make a large purchase whether it be groceries or a Christmas gift. I also have ADHD and can identify with what you are feeling. Have you gone back and crushed your numbers again now that you have made the purchase? You said you used money from savings and that you had been saving up. It's my opinion that it is ok to not know what you are saving for and also that it is ok to start early on Christmas. Heck I start grabbing things here and there as early as July! If it were me I would take some deep breaths, ground myself in the moment and go back to my budget to see how the purchase impacted my budget in comparison to my debt through December. If u feel you may need that money it may not be too late to cancel the order. However if u still feel you will manage until next month consider keeping things as they are. That's what I would do. Hope this helps and I bet your husband will LOVE his gift! Keep us posted!
