"personal truth"

I was in Ithaca once as a freshman with c and some old friends who have grown up and gone away since then, and we went to a coffee shop where a hippie woman gave us free mate and talked to us about personal truth. I can't remember exactly what she said, but Oedipus Rex was brought up in our argument against her, and we thought we were so brilliant because we had read it and argued circles around this woman, who was illogical, but just had a different opinion than we did.  We thought we knew so much, about how Oedipus' personal truth led to the truth, and how it affected his world.  Years later, in our theory of knowledge class, we were told that there was no such thing as personal truth; there is only the truth, and then there are our perceptions of the truth.  I personally don't see the difference, aren't personal truth and perception the same thing? Right now everything looks darker to me, and I am "perceiving" that we aren't talking, and I'm perceiving that I'm drawing away from everyone, even though that's not what I want, or need.  My personal truth is that I'm losing them, all of them, and it's my own fault.
