I was diagnosed with BPD at a mental hospital after an inpatient stay there...then my therapist said I probably had CPTSD, and then a few years later the same mental hospital told me I may have PTSD.  So I don't really know which of these I have, or if I have both, but a huge problem I have had is obsession.  Generally when I would go through a break up in the past I would obsess over it until I reached the point of wanting to kill myself.  But nowadays I am married and haven't had a break up in years, so instead I obsess over bad things people have said to me or ways I have been wronged.  I can stay angry for weeks, months, or even years over a relatively minor incident.   I feel like obsessing over the past has really fucked me up.  Anyways I wanted to know if this was normal.  Thanks.
