We have all got PTSD, more or less. It must be addressed.
UnforgivenII, we don't all have PTSD.  :)epression is probably the most common issue here. Many members have attachment insecurities. There is no, one size fits all.

Caretaker2, infidelity will rock your world. You live near a major medical school with a good psychiatry department. I would suggest seeing a psychiatrist there to get a meds evaluation, talk about treatment and have him refer you to a PhD psychologist. He will want to see you periodically to monitor the meds and you can tell him how counseling is going and evaluate possible shifts you may want to take in treatment directions.
Have you taken the depression test here?
If you have trust issues, it would seem to me that its important to find out if this is a commutative life experiences thing or a situational thing - likely it is the former.
