Feeling alone.

I'm quite social, I love people, and people genuinely like me. I always have a group to hang out with. Yet I don't feel like I have anyone I can actually talk to about my problems...nobody cares enough. My problem is not being included, my problem is that people want to be seen with me but don't actually care about me. And I have anxiety and a lot going on in my life but nobody to talk it out with, leaving me constantly depressed. How can I find a real friend? (I am trying very hard to be a good friend to others, doesn't help much. And I don't want to be clingy!)
