Hi. I am having a hard time lately explaining to friends and family why I am more withdrawn these days, especially to those who do not understand and see this withdrawal as me "not making an effort for our friendship".

Essentially, my auditory hallucinations have increased over the past few years, and I find myself at the end of the day exhausted because I have had a whole day's worth of conversations in my head; I don't want to talk to anyone else. I see my close friends bi-weekly on average, and my other friends every 2-3 months. For further context, I both study and work full-time so often am having to complete deadlines which are time consuming.

So anyway, I have explained to my friends my disorder, including what it entails, what everything means, what I mostly am prone to, and how if I withdraw literally no offense is meant. My very close friends and family and partner are extremely understanding and have had no qualms.
But I have one particular friend who just doesn't seem to get it. She thinks that because I don't message her every day like I used to (i.e. when I thought I "had" to message everyone every day or people would hate me) that I don't care for our friendship. When we do talk and catch up she has nothing to say; which is what irks me. Nothing is happening in her life, and when we talk about current affairs she is very ignorant and/or ill-informed. Educating her is impossible, which leads me to believe that this may be why she doesn't understand how BPD works. But her husband has Bipolar Disorder, so how could she not understand to some degree?

I spent so long thinking I was a terrible friend, but now I know I am entitled to withdraw if I don't feel comfortable always being sociable - which is the case because I am an extroverted introvert - so long as I still do make the effort for my friendships. Also, as everyone else has understood and is compassionate, this is another reason for me to believe that maybe she just doesn't get it?

I don't know. I guess what I am trying to say (or ask), is how do I further educate her so she does understand? Or should I let the friendship go? I try really hard to keep my interpersonal relationships afloat, but when they're marred by the other person making me feel bad, it becomes increasingly difficult.

TLDR; Friend doesn't understand BPD, has made no effort to understand BPD, and thinks I am a bad friend. Am I bad? How to I educate? Should I let friendship go?
