B4: I agree with rhoch. I would also suggest you keep a separate journal of her behavior and mood swings etc..
No "counselor" will ever pick up on these things. Why ? Just like my w.. when she presents herself she seems "fine"..she should have been nominated for an Academy Award . the only time she shows her symptoms is with me and kids... unless you really know what to look for with her.
These illnesses manifest themselves differently and different ages in each individual and with varying severity. One thing that is a given..It is a rollercoaster ride. Oh.. and paranoia is a specific symptom of BPD from what I know.. also the detachment.. and the "fear of abandonment" (ie. remember when she thought divorce was you coming over and mowing yard etc.. ??)
