Why can’t I establish or maintain decent friendships?

I am twenty years old, and I am almost a senior in college. I essentially have no friends whatsoever. I only managed to procure a minuscule amount of friends in high school, but only one of them still occasionally converses with me. However, it is a chore for me to tolerate her because she has no job, no education, no ambitions, etc. All she does is leech off the welfare system and hardworking citizens and smoke marijuana or drink alcoholic beverages all day. The rest of my previous friends from high school are pregnant, already have reproduced, or are in jail and or awaiting arrest. Throughout my years in college, I attempted to establish friendships, but no potential friends corresponded to my expectations. Elaborating on the aforementioned statement, all the potential friends I meet disgust me to the point where they become intolerable, as they are merely concerned with drinking, partying, and sexual escapades. I attempted to compromise with my expectations, and I attended several inane college parties, which I still fail to comprehend the point of. Through extensive research and observation of the typical behavior of my peers, I discovered that my apathetic attitude toward alcohol and my virginity/modesty are social hindrances because they are apparently not considered “cool”, as they are postulated as snobbishness instead. Is there any manner in which to procure friends who are not losers without compromising my values or should I prepare for a life of solitude? I do not intend to sound sardonic or acerbic, but I am frustrated that I cannot procure at least one decent friend.
