hi Tammie, and

first things first: a diagnosis of BPD, or anxiety, or major depression, or for that matter, a damaged tooth, can be life changing.
and frankly, thats often in a way that things get worse before they get better. its a little bit like being told the sky is actually green, and learning to adapt to that, except it has far greater implications on your life.
so while a diagnosis can be invaluable, ultimately, it can make things worse for your partner and your relationship in the near term.
it sounds like theres some conflict going on. tell us more about it. whats going on between the two of you lately?
