Why am I so unlikeable

I’m 22 (f) living in the uk and I don’t think I know anyone who knows me well and still likes me. I’m a quite extroverted person and have a fairly loud personality growing up my sister would bully me quite a lot (I played a major role in a Oscar nominated movie and I think she was just jealous) I was quite a confident kid but took a long time to grow up and was childish well into my teens. I had a few close friendships but they fizzled or people would just stop speaking to me I made a best friend when I was about 8 years old and I was also (or so I thought) really close with a guy in my school as we’d always go back home together. My best friend decided she didn’t want to be friends anymore because I had an abrtin and the guy basically told me straight up he never really thought of me as close and just an acquaintance these two situations happened a bit over a year ago and I haven’t gotten over them one bit. They made me realize I’m extremely unlikeable, I’m not exactly lonely but I feel so incredibly insecure I like myself and the people who are still distant friends with me seem to like me, does anyone know what does it mean if you just aren’t really likeable? Is there anything I can do or should I just accept it
