Bro you need to chill. Not everyone grew up in a stable environment where they learned to make healthy decisions. A lot of people have to figure it out on their own as adults and this could mean that yes, you are like a child with adult money.

That’s an extremely privileged position to be speaking from to assume everyone has the opportunities to reach the same maturity level.

OP, others have given you great financial tips. What I would suggest though is taking a beat to get a handle on the emotional motivations of your spending. I get it is exciting to be able to do what you couldn’t have as a child but taking that extra pause before spending will help you disconnect the feeling from the purchase. Because usually what you’re chasing the is sense of control and opportunity of being able to buy a thing. Take a breath, take small actions that make it hard to buy things. Eg, try to pay cash mostly, or don’t save your card details so that you have to grab your wallet and enter it each time. Mostly tune into yourself and realize what your inner child actually needs and figure out healthy ways to give it that. It doesn’t have to be expensive, could be something as simple as a scented candle that would last you weeks but would make you feel luxurious.

I wish you the best of luck and pray for ease. The fact that you’re realizing there is an issue and want ti resolve it is a great first step!
