Depression and Anxiety

Lately I think I am being either depressed or having some sort of anxiety.  It is because of my 26 year old daughter who is leaving in the New England area and has not been home for almost a year.  She is working up there and about a month ago she quit her job and was planning to move to the South to leave either at home with us or with her sister in Tennesse.  I have to say that she lies to me a lot.  My husband and daughter are telling me that I am interfering in her life a lot and that is why she keeps on making up stories about different matters just to please me.  I don't know what to do.  The other day she told me that she got a job exactly the day that she was supposed to leave New England and now she is going to stay there.  My problem is that I cannot trust her and I think that she is lying again.  Please someone help me and give me an advise to what should I do?  Am I messed up in my head?  We all have missed her alot.
