Hi everyone. One of my best friends was recently diagnosed with BPD. They're in a bit of a crisis at the moment - had to move back in with their parents but after some mutual aid via a gofundme they'll be able to move into a new apartment and start therapy as well.

For some background, I've known them for around 4-5 years. They're a very sweet, intelligent person, a joy to be around. Unfortunately, they've been subjected to various forms of trauma throughout their life. I'm one of their only friends. Prior to their diagnosis there were times where they'd stop talking to me after a minor dispute (random arguments between friends for example, disagreements about other things). We recently started talking again after a few months of no contact, and they shared with me their diagnosis. 

I watched a video on youtube on what it's like to live with BPD, and I'm trying to find some books about how to best support loved ones who have it. At the moment, I do my best to listen to them and validate their feelings. However, I'm also fearful of them being reliant on me for support. Is that a valid fear to have? I understand that might be hard to answer cause everyone's case is unique. That being said, what are some resources for someone in my situation to best support my friend?

Thanks.
