Missed flight and feel stupid

I read the ticket wrong for my flight. Read it as 1pm which is stupid considering most airlines use a 24 hour system. Ik this cause I’ve flown before I just don’t know what I was thinking. I feel bad cause it was an expensive flight and my father lent me the money and it feels like I just flushed his money down the drain. I’m trying to see the blessings in what’s bad (wounds dramatic but maybe somehow I just wasn’t meant to get on that flight cause something bad could have happened) and understand that we all make stupid mistakes.
