Statistically people are happier and healthier than any time in history. Even if you don't like politics, the vast majority of policy passed in places like the USA and EU does improve life there. The dictators like Ji Xinping and Vladimir Putin are past their prime by a long shot. The children of the rich vocally hate their parents. People at the highest level of power are being held to high standards and made responsible for their crimes.

The one statistically noteworthy thing there is to worry about is Climate Change, sadly 2022 was a new high for total emissions in billion tons, but the next generation wants to do away with cars, with fossil fuels, with nonrecyclables entirely so if we can just survive that crisis it should be all good.

Even Gun Violence is just a rounding error probability that it would affect you at all. Something like ~0.00003125% of the total global population died from firearms in 2019, admittedly that percentage goes up in places like the USA, Mexico, and St Kitts, but it's pretty negligible for the everyday life of the average person. I'm sorry if it sounds like I'm diminishing the problem here, but I think you can want to fix the problem without worrying how it affects you personally.
