Welcome, Kelly. It's great you are so open and willing to learn about BPD for the sake of your daughter and coming from a place of wanting to help her.

BPD is a complicated diagnosis and the symptoms, triggers, and profile are different for everyone. This forum is a wealth of information and I think others who have been in your shoes may have a lot to offer.

That being said, to get started, NAMI is a great source of reliable info on mental illness including BPD. BPD Central and BPD Family are some other websites. There's lots of great books out there too.

Some families find in person support can be helpful too, so seeking out a local support group for caregivers may be something to consider. Again it can be really help to connect with others who can relate to what you're going through and learn from them. Mental Health America is one place to look, NAMI may also list some local support groups.

Also remember to take care of yourself. Caring for someone with mental illness can be taxing and bring up a lot of different emotions. Making time for your own well being and self care is so important!
