Dear Hannah:
Reads to me that you are tired, frustrated, disappointed and a bit lost, but not “a pathological liar, determined to self destruct”. I think are exaggerating your wrong doing: convenient lying (that is, you told people you have a stomach bug because you don’t feel like telling them the truth) is not the same as pathological lying.
I suppose you had certain plans that didn’t work out so far and you compromised, taking on this job because it made sense to do that, but living the compromised life doesn’t feel as good as the dream or dreams you had before, how you hoped your life would be. Am I correct?
