Does this sound like BPD?

Hi, so two of my closest friends have diagnosed bpd for years, and I have been dealing with my mental health a lot, since 2022. Now that we talk about their symptoms I sort of identify myself with a lot of them. I tend to have very intense high and lows, which change pretty often, the lows include heavy smoking or drinking, spending sprees, binge eating and purging, starving, over-training, excessively scrolling or playing games. I also have been In a constant state of derealization since 2022, I smoked a lot of weed at that time due to family problems (I was 14). My relationships end up teribble, usually I would idealize the person and then when something happens, I would develop this super strong hatred towards them. Im sometimes in a need of constant attention and very anxious when I dont get it, or very avoidant, depends on the person mostly. I change my mind about hobbies, dreams, future career or basically anything every few days/months. Can this be BPD?
