how to not feel guilty

ugh, I don't know if I should be feeling so, but I saw a dress while browsing, it was in my favorite color, i see that I had already wishlisted it but hadn't bought it.

I see that it's been priced very reasonably but then I see that another buyer is asking queries to buy the dress but I buy it anyway. seller has confirmed my shipping, but now I feel a little bad that I bought that dress despite knowing somebody else was going to buy it 😭 but it's not like I bought it out spite or any ill will (like Idek the other buyer much less why would I waste money over such a silly notion)

the other buyer is asking the seller to cancel my order and I do feel a little not so nice and thinking of cancelling it myself 🤧
