I'm literally so fucking cooked

we have a celebration outing thing from my local coaching, for the students who made it. it's a full day 12 hours thing. i came back from an 8 day outing like- day before yesterday, my muscles haven't recovered from that yet, I'm in genuine pain, and my family is forcing me to go, saying it's a good opportunity.

i never made friends with those people, they're still always talking about studies and stuff, just cleared neet ug and they're already taking about colleges for pg (which will be after they finish the degree they haven't started yet). meanwhile i still haven't properly researched the colleges I'm applying for in under a month

how the hell am i supposed to survive these awkward 12 hours? i feel like being on my phone for almost all the time there will be rude, but like can i do anything else? I've genuinely never talked to anyone there except for the two times i went for celebration parties at different centres.
