Been in Charlotte for almost 4 years and I feel like I'm trying to squeeze water out of a rock, anyone feel the same?

I've done everything there is to do, I've gone to all the clubs and meetups, did all the yearly things that come to the city, and now I just don't know what to do. Feels like my friends are moving out or settling down and just kind of drift away. I meet lots of friendly people but maybe 1 out of 100 will want to even hang out with me or attempt to pursue a deeper friendship. 3 years ago, it was the exact opposite. I was making so many friends. My Birthday parties were awesome, crazy action filled weekends, and now I feel like all of that is slowly evaporating.
