Wrong decision or not

Dear coaches,
I made the decision to pay myself first to keep my salary at the same level as last year. I could have decided to take less salary and put more into my research program. At the time, I felt confident because I thought everything will work out fine. Now I think its the wrong decision because I’m worried about the future and uncertain how things will work out. I sometimes feel almost nauseous that I made a terrible mistake. Interesting that nothing in the circumstance has changed, just fear and worry from uncertainty. I’m kind of going back and forth with trying to manage my mind. Accept i made a mistake and try to fix it or decide that I made the right choice at the time and coach myself around allowing the feeling of uncertainty to be ok? I guess I’m just adding to the problem with indecision. Any advice? Thank you.
