Various factors can cause stress by tracking spending.
Overspending on unnecessary items can be a source of shame or failure. Insufficient income for basic needs or desires is a huge stressor and has been contributed to by the last few years of higher inflation. Wages generally have not kept up with inflation, leading to tight budgets that are limited or, in many cases, people being unable to meet basic needs. Tracking spending when a lot of the budget is going towards debt is often a considerable source of stress.
However, people with more than enough money still feel stressed about spending. They do not find security even when they have no financial worries outside of an economic collapse.
A few suggestions to hopefully help people have a healthier relationship with money.
Start with a small emergency fund
Have a plan to eliminate debt that starts by paying off the smallest debt first. The sense of momentum and accomplishment can encourage one to stay on track. Debt is usually a behavioral problem and not just a math problem.
If married, learn to work on the budgeting and spending together. Teamwork can be the key to success.
Have a place for every dollar to go
Do not allow your identity, self-worth, or security to come only from money.
My experience in helping people with their budgeting and planning is that they do better when they have a long-term view with a set of goals. The plan needs to be supported with education and facts. A sense of purpose in life includes a person's money, and it needs to be aligned.
