Hi wandafull,
I wanted to join lbjnltx in welcoming you to the site, and to say how much I admire your self-awareness, and your courage to look so honestly at things. I heard someone say that suffering occurs whenever we lack control over something. That can be anything from a red light when you're running late, to the excruciating pain of feeling we can't do enough for our kids. I notice for myself that the suffering seems to lessen when I acknowledge what I do have control over, which is usually just myself. Doing this has had a big effect on my son, which is the darnedest thing!
You mention that your daughter is in therapy, and that it seems to be helping. Does she acknowledge that she is BPD? Is she receiving any particular type of therapeutic approach, or taking any medications?
My son's psychiatrist talked about epigenetics with me -- which (as best as I can make sense of), is about how genes can change over time in response to the environment. So the DNA can be there, sleeping, and then certain expressions of that gene are triggered by environmental conditions. He even said there are studies about transgenerational influences, including how a traumatic experience in one generation can trigger fear responses in the next generations (those studies were done on mice, though, not humans). I found this describing epigenetics online:
"According to a popular metaphor, our genes themselves may be written in ink, but they're marked up in pencil—which can be erased and re-done. By developing drugs or treatments that modify these pencil marks, so the thinking goes, we can escape the limits imposed by our genes, which can't be changed."
Anyway. Sorry to get so nerdy about this. I felt really guilty about my son's depression and anxiety, and tried to figure out who caused it, who made it happen, who didn't fix it, and all kinds of things that just made me feel bad and didn't help S13. And I guess this view helped me realize that it's a dialog between genetics and the environment. Since I'm part of that environment, and I'm the only person I can truly control, I just decided to focus on what I can do, using tools and communication to try and improve what I could.
Care about your depression. If you dig into it, there may be a whole bunch of wonderful emotions buried in there that are ready to see the sunlight. I had this weird experience a year ago when I felt something and couldn't figure out what it was, and then realized it felt like a combination of happiness and pain, and my therapist said it sounds like joy, and that it hurts because you haven't felt it for so long
