Ambien and dismay

I have been Ambien for about 3 years. I finally get a good nights sleep. I look forward to the little white pill which gives me rest. Recently, much to my dismay I have been experiencing something that really troubles me. I have to assume it is Ambien because nothing else has changed with me. I have become very paranoid with my friends. I don;t know how else to explain it. Other than that and that is huge, because I am constantly looking over my shoulder for something I have done, I am beginning to trust no one. Is anyone else experiencing any of this? I am typically a friendly easy going person with a lot of friends but in the past year things have changed. I've accused friends of things and have lost a lot of their friendships. I can't afford to lose anymore no matter how nice I might be,(or I think I am) I am beginning to question myself. Am I going nuts or is it possibly the little pill that gets me through the night. Can anyone help me with this dilemma, I can't afford to lose any more friends or loved ones. Help! I'm going to try to go off my little pill that brings peace to my life but I have to know if I'm going crazy or is it the medication. This is my last night to use it I think.
