So what are you doing about it? You seem to want validation from us - which isn't a bad thing. Venting can be so very therapeutic. But what have you done to deal with this and react? Have you told these people you caught them in lies? Have you told them you haven't appreciated the dishonesty?

Again, evaluate the dishonesty and what was intended by it. Is it possible they thought doing so was of benefit (did they think in the grand picture that they might have been helping you?). Or were these lies intended to hurt you.

I suppose what it has come down to is that you need to look at your circle of friends and (if these lies were intended to damage and hurt you) cull them and walk away.

It is really important that you inform your doctor of this. S/he needs to know that you are convinced everyone is persecuting you. They will have their own ideas regarding this.
