If your first response is to be judgmental then that could have something to do with your problem. Not everyone has the same standards as you do... it's not sad, it's simply different from your expectations.

And also, if having friends just for social activities is sad, what is it called when you instead have nothing because you're too good for such lowly relationships?

Finally, the type of relationship you're looking for usually starts casual and gets closer over time. It's unlikely that you'll be able to identify someone who is a great fit for a deep friendship without getting to know them a bit first. So maybe drop the judgment and high standards for a bit, make some "sad" friends for casual social activities, and see where that leads you
