man I can understand being an introvert since I've been alone through most of my school life having only a few good friends. But I won't go into it anymore since I don't know the full story. The people who have tons of "friends" are usually bad people.
Only true friends I have in my case are my mom n dad for sure. A true friend is a person who'd put down his/her life for you, and in that case, my parents are the only who fit it that I know for sure. Good friends are people that don't gossip, steal, do drugs, don't lie, try to help, don't talk bad about others (they do this, they'll talk about you if you slip even a little) etc. Those are also rare. But as for parties- I don't really care much for them. You usually find trash there, and it's a gossip fest anyway.
For the true ones, you may only find 1 in this lifetime since they're so rare to come by. For good friends, maybe 2-3 at most. Those good friends are my seniors, though, and they'll be moving on to college next year. However, I can have a long connection to them.
Based on these standards, I wouldn't really take a "friendship" seriously. The other "friends" that're there are just there. They'll disappear through the course of time like a bunch I've seen. It just happens sometimes
