Depends on what you want to achieve. You can look for short term happiness or you can work on addressing what is making you unhappy.
Short term is easy for me. I grab a six pack and a book and go down to the river and read and drink. My sister shops. Different strokes for different folks. What you might like is impossible for us to know.
The thing is the problem doesn’t vanish. I can polish off a six pack and a book and the problem is still there. My sister can buy a new pair of shoes and the problems are still there when she gets home.
So what I usually try to do is accept the problem. No amount of “If only I had done this” will ever fix a problem. Once you accept reality you can then decide how to correct it. Or at least make it hurt as little as possible.
