Just got diagnosed with bpd

Hey everyone, I am a 19 F. I have been struggling with my mental health since I was 11... With the sh thoughts to suicidal thoughts... and it has always felt like I am just a pretend who observes and imitates the people I meet. I hate my body and everything about me and have really bad anxiety. The level of paranoia I have and the amount of weird thoughts I have make me sometimes feel like I am going insane... But today after a lot of assessments my therapist finally concluded that I have borderline personality disorder. And It felt like things finally make sense. I believe I have masked my feeling my whole life and it took me a long time to actually open up to my therapist and I know that there are a lot of things still not told by me but I feel a sense of relief. So I guess why I am writing this is so that I can get some tips on how to manage. Even tho I have lived with it till now I am still confused and would love a bit of help.

Thanks for reading<3
