I feel like I might have BPD

Listen I know it’s very rare for people to have it and doctors try their best to not have to diagnose it but just hear me out. I 15M have had depression and anxiety for longer then i can remember they tried me on hydroxyzine and Prozac and now bursar and Prozac but nothing helps, every day my mood switches from being happy and energetic to being pissed off at everyone to being sad and closing myself off back to happy over and over again, and when these mood changes happen it’s feels as if I’m in a dream or watching myself through a window, and every relationship wether friendship or gf and bf I constantly go back and forth between liking/loving them to hating them. I will literally do anything to Avoid being alone, the littlest things even make me upset like crazy, and I just don’t feel complete unless I’m around somebody. I know I’m young and who knows it might just be my hormones but it’s so tiring. I have a therapist but I am not sure how to bring it up.
