Hi SweepeaSmile,
I want to join Kamina and say Welcome too!
I'm on this site because my SO (significant other) has 2 daughters with an uBPDxw (undiagnosed BPD ex-wife). You are not alone in your feelings of anxiety and depression... .My SO's older daughter has periods of depression and my SO's younger daughter has been diagnosed with PTSD. There are alot of chaos, instability, and hurtful behaviors that they both have had to cope with in terms of their mom and I imagine you have experienced similar stuff.
Can you share a little bit more of your story? Do you live with your mom? Are you out on your own? Married? Do you have any Siblings? What behaviors are you seeing from your mom that led you to BPD?
I stumbled upon BPD by doing a Google search on "Chronic Lying" though my SO's ex has not been diagnosed the shoe unfortunately fits
I have found this website very helpful in terms of support, ideas, tools and a good place to vent when I've needed to

I know you will too.
Take Care,
