I (19F) have never been officially diagnosed with BPD, but I have been seeing a therapist. I show many symptoms and it has begun to take a massive toll on my life. I realized I could possibly have BPD when I began making irrational decisions that hurt my ex-partner. I am ashamed of how I behaved and after she cut me out of her life I decided I wanted to get better. 

I am now seeing a guy that I am absolutely infatuated with. I can already tell he has become my favorite person and I do not like that. I hate having a favorite person, for that is when I become the most anxious and irrational. I want things to work out between us, so I've had to unlearn a lot of my previous bad habits. I've been trying to remind myself that boundaries are not rejection, rather, they are healthy lines of space between people. 

Personally, I feel like many people within the BPD community do not want to get better. A part of me understands why, because coping with BPD is a lonely road. When I split, all I want to do is reach out to someone. However, I know it is healthier to stick to myself and allow the sea of emotions to pass. I do not want my delusions to get the best of me, and I want to be self-aware.

What is the best advice you can give to someone with this disorder who is looking to better themselves and their relationships? 

TL;DR: I'm pretty sure I have BPD and I want to overcome it. Advice is much appreciated.
