I hung out with my sisters friends and **** got messy?

so i hung out with my sisters friends who are way older than me and i remember smoking **** loads of pot and drinking loads, i threw up and **** which is pretty normal, but i feel so degraded and childish because of the way i get treated, i felt way out of place and would have prefered if it was my friends i was hanging out with. I felt so degraded, childish, and stupid. I mean I kept getting told to do what I want i mean how do I do that with people Ive never met, i have nothing incommon with them they were all crazy. I just hate this feeling I have is there any explanation and solution if so thank you in advance for you help and time.
