@enthusiasticTree4598 Hi Gina,
The great thing about your sons diagnosis is that now he can start moving towards managing it, and building a life worth living. :)
Remember, your son is the same person he was before the diagnosis. Nothing has changed, except now you have a name for what he has been struggling with, and now you will be better able to access supports and programs to help him.
There is a wonderful treatment option designed for people who struggle with BPD, it is called DBT (Dialectical Behavioral Therapy). I encourage you to google it. It is largly skills based, and many people have found that their BPD can actually be managed by developing and using these skills.
I was diagnosed with BPD 1.5 years ago... I have found the DBT skills very valuable and helpful. I am only just begining a formal DBT program now, but I found I was able to learn many DBT skills by reading up on them. There are some GREAT books out there that give you the information to get started.
The first books I bought were 'Borderline Personality Disorder for Dummies', and 'Borderline Personality Disorder: A guide for the newly diagonsed.' I recomend them both as a good place to start.
*hugs* and all the best.
