Is it bad if a best friend trusts you way too much?

The only friend I trust is my best friend. I have other good friends but my best friend is the only one I can really trust. I prefer to hang out with her over everyone else. Don't get me wrong, I love my other friends, but I don't trust them like I trust my best friend the most. If someone asks which two people I trust the most. It would be hard bit I pick my best friend and my dad. My best friend is the only one I can trust in my group of friends. The others I let go. Sometimes it's better to have 1 true friend over 100 fake ones.
