I'm losing relationships

I wish I could say with confidence, I always feel like at least one person will always be there for me. I can't say as to why I feel like no one around me truly connects with me. I feel distant in my normal group of friends. I don't rely on them as much as I used to and although we still talk quite a bit, I don't think of them as those that I trust the most. Maybe two of my friends I find myself feeling an actual connection to, but it's not the strongest. I want to think that I feel like I have a great friend group but I don't even know if they're all so great to be with anymore. I just feel really distant from them and I don't even know anymore if I should try to regain our friendship.
