Though your situation may feel hopeless, it is familiar to many BPD families and can improve.
Our family had been in a vicious cycle for 18 months; repeated hospitalizations, med changes, IOP, PHP 3x/ea. We felt we weren't getting anywhere. Her last hospitalization was this past December and at that time it was decided she be placed in a residential program. Though it wasn't our first choice, we had tried everything else and the suicidal thoughts were too much to handle

home. It is now 7 months since placement and we have grown soo much as a family. During this time her meds have changed, support has been consistent in therapy home setting, family has received weekly sessions and we have learned more effective communication. Take a look at the tools to the right to get yourself started.
I'm here to tell you that you're not alone and many have walked similar paths; it can get better.
