Should I feel guilt for taking time off work? Using my PTO

My brothers and dad told me I need to be careful what choices I’m making and my job ALWAYS GOES FIRST. I can’t just take off like that and it was a HUGE risk I took. I mean they do have a point but my boss said she was okay with it and the teacher said she was okay with too and I asked if they’re going to be okay and they said they will be okay thanks for checking in. I’m on my way to a three day weekend trip and we left this morning and now I’m already feeling a little guilty thanks to my dad and brothers! I mean it’s PTO and it’s PAID TIME OFF. I mean what’s the point of having it if we don’t use it. From now on I’m only going to use it for important things. I know my family is going to give me that same lecture if I told them.
I mean it’s already been approved and done so I’m on my way right now. The other staff doesn’t know why I didn’t come in to work and it’s none of their business.
Even my best friend said, “Girl that was a HUGE risk you took. You only worked there for a month and already taking time off. That’s stupid. You won’t get paid and do you really think they meant that they’re really OK with it?”
I told her it’s PAID TIME OFF. She said it doesn’t matter and I shouldn’t of took that day off in the first place I should feel guilty about it and my dad and brothers are right. I’m not gonna make it into a habit or anything.
