How do you spend without guilt?

Hi, I am 24F and working for 2 jobs as an offshore accountant for an AU-based and US-based company. I earn pretty well for myself. For context, I am not a breadwinner, I earn a minimum of Php100k in a month, I do have some responsibilities in my family, but I am generally able to save a minimum of 70k in a month and was able to save more than 500k so far. However, whenever I have to make big spendings for myself, I feel guilty. I have a 10-day trip coming up and for the flights and accommodations, I have spent more than 30k already, now the thing is I FEEL SO GUILTY spending this much for a few days.

How do you guys deal with this? I want to enjoy my earnings but I'm also scared to screw up.
