I feel like I'm being Excluded, HELP!?

Me and my freind, let's call her Lulu, have been freinds all our lives. We have always been really really close, but later I've just been feeling that shes been ignoring me or excluding me and sort of treating me like a little yappy dog. There is this girl, we shall call her Hannah, who has been hanging out with her alot more, kind of in my place. Anyway they keep organizing events and stuff and "forgetting" to tell me, and when I do ask to come they just act really distant or make up dumb excuses. Anyway thanks, and please please dont just tell me to "get new freinds" because that's a damn lot easier said than done. Thanks. XxXxXxXx
