I feel extremely guilty after buying a laptop

Hello !

I've made a purchase today (well yesterday, it's 4:30 right now), it's a laptop with a processor i was looking for and was planning to spend 900€ maximum but ended up buying one for 1165€.

I'm an IT student who's already taking on few projects for friends and myself so i wanted one which would allow me to work outside of home for more than 3h ans my previous laptop was no fit so i sold it for 450€.

But now that i used it a bit, it's a nice laptop but i'm overwhelmed by a feeling of guilt and regret to the point i'm unable to sleep, i know i'll make that money back soon but i can't stop regretting that purchase despite being what i wanted and i'm planning to return it tomorrow if i can

Anyone who's struggling with these kind of feelings after spending huge amount of money ?

I grew up really poor and only stopped struggling recently so i was thrilled about buying a brand new laptop and not worry about emptying my bank account but now i feel like i've made the worst decision possible.
