Everything revolves around money

I've never really cared about money. I have all I need in life and sure, more money would be pretty useful, like I could go on trips for holidays or buy lots of clothes and similar things, but other than that, it's not so necessary.

My family is kind of lower middle class and we usually don't have any major problems concerning money, but when I need to go on class trips abroad, it's always a bit difficult for my parents to give that much money for like two or three days.

 For example- I'm supposed to go on this class trip for two days to a country that's 6 hours away and it costs 200$. I mean come on, two days. I feel SO guilty having to ask my parents for money because I know they don't have it and I feel bad trying to lower our class' costs because no one else seems to care how much money we spend. Ugh. It's so ridiculous and I can't really talk to anyone so here you go Internet.
