I just learned about BPD paranoia??

I just went through something that I had no idea was even apart of BPD yet alone that I was going through it. It felt like a complete fact that my brain was telling me. So a few days ago, my two friends didn’t talk to me as much naturally due to classes they had together. Also during a small break in the class they went and walked together down the halls and didn’t even invite me, and in the next class it seemed like they didn’t even want to talk to me, And when they left the last class they didn’t wait for me so I just assumed they found me annoying and hated me so I just stopped talking to them (They literally said bye to me when I left and invited me to hangout for bowling the next day). I just still think they secretly find me annoying and I need to back away from them so that perception of me can go away before they begin to dislike me more (in sixth grade I had a best friend who loudly shouted at me “YOURE ANNOYING!”, out of nowhere and told me to go.) I cannot tell if people hate me or not if they don’t tell me and I just assume they don’t like me, even though there hasn’t been any evidence of it. Am I being paranoid???
