Do I love my best friend a little too much?

I mean, in a certain sense, there's no such thing as loving your best friend too much, but I think I may be getting way too insecure about him. He lives two states away and I think that may be playing a role in how I feel kinda powerless to help protect him from wrongdoing, but I'm starting to feel like I'm getting obsessed. I've never had the greatest social life, so maybe I'm just overcompensating. Either way, I don't want to screw our friendship because he's the only person who has ever truly accepted me for who I am. Maybe him being two states away isn't helping. Has anyone else ever experienced this before? Any feedback would be appreciated (but not rude or spam comments, thanks). I just know I have never come by friends like this often and I don't want to make the wrong moves and ruin it.
