What are you actually expecting to see on a personal level?
The main changes Brexit brought with it were to do with law making, governing, import/export and savings on the membership fee.
If your only counterclaim is "where's all the money for the NHS?" then you clearly haven't bothered to do any research. If you look it up, you'd see that from the tax year 2019/20 to 2022/23 the NHS budget has increased by over 15%, which is around £30 billion a year extra. This does not include the additional £50 billion during the main Covid spike in 2020/21.
You also need to understand that the current inflation, knock back effects from the war in Ukraine, gas/electric price changes, food prices changes has no correlation with Brexit, and are separate things.
The UK government has never given out so many hand outs than they have in the last few years, from protecting businesses and jobs during Covid, to the energy price guarantee, to increasing minimum wage dramatically, to all the cost of living handouts.
So please tell me, what else you are waiting to happen?
