Can someone from St. Andrews help me?

This is my first year here at St. Andrews and so far I am enjoying myself.
I've made some nice friends and I really love my hall so hardly any complaints, bar one.
While all my friends and most people on my courses have been adopted I have yet to find my academic parents. I'm incredibly shy unfortunately and so I haven't had much luck with speaking to many third years apart from a few but they're all either not adopting or already have children.
It's making me feel quite anxious as I know raisin weekend is big here and all my friends have had dinners or went out with their mums and dads and it's slightly disheartening.
Basically would it be taboo or seem strange if I went home for raisin weekend as it runs into independent reading week? I keep checking flight prices as well but I'm at a loss.
Any and all advice would be greatly appreciated!!
