My best friend of 12+ years has BPD. She was only definitively diagnosed within the past 3 years &amp; so she is still learning to cope &amp; im still learning how to have the healthiest relationship possible with someone I adore but also take criticism very hard. 

Whenever she has stress or drama going on, it’s all she sees. She will full well know I’m at home alone with my 3yo twins dealing with my own mental health issues &amp; my own crazy family, but still text or call me saying how badly she needs to talk to me or come over bc she’s having such a bad day or is struggling &amp; she needs me. 

I know she cares about the problems in my life just as much as I do hers. I know this is classic BPD tendencies, but how can I tell her that it makes me feel insignificant &amp; unseen when she gets in this way of thinking? The whiny bitch in me wants to say “you don’t hold a monopoly on stress, anxiety &amp; depression...other people have problems too &amp; I don’t have the energy to juggle them for both of us”, but I don’t want to say that bc I know it’s not intentional or conscious.

I just want a nonconfrontational way of bringing her back to a more balanced friendship.
