Hello Cosamom and

You're in good company with others who are also navigating very challenging, very emotionally intense family relationships. We do get it here.
After years of struggling with my son’s mental health and suicide ideation, we have arrived at BPD.
Did he receive a diagnosis? If so, is he accepting of it?
How old is he now, and when did you first start seeing signs that something was off?
I tried to set some boundaries but just ended up hurt, exhausted and crying.
Tell me some more about that. What boundaries did you try to set? How did you approach that? There may be ways for you to improve your
boundary skills, which are really just rules we have for ourselves (not others) that are under our control.
I feel trapped in my home and my life. Whenever I do something for me, I pay for it with him.
Is he violent?
I just need someone who gets it because my friends just think he’s being a spoiled jerk and it it’s so much more than that. I can’t really talk to them about it so I’m lonely and isolated too.
These are difficult and often unintuitive relationships, especially because if he really does have BPD, then he has a real, serious, and impairing mental illness -- not just a "phase". Like PearlsBefore mentioned:
one thing that did help me a bit was the advice to learn to be able to visualise them basically in a hospital gown as though they're home on bedrest - when they're not. It helps to be a little more patient if you can remind yourself they kinda of are...a patient.
If BPD is in play, then your son does have serious mental wellness challenges (not insurmountable, but currently very challenging), even if there are times when he seems "normal".
As you settle in here, take a look at our articles on
