Is it normal im sick of my mum telling me i'm different because it makes me....

Feel like a looser :/
She doesn't say it all the time but when she does, she goes on talking about how I'm different from all the rest of the people/my friends. Today she was talking about my last friends and how they were negative energy/heavy energy. I used to associate with them years ago, smoke pot a bit & drink for fun. My mum says they changed me and my appearance even changed a bit too. I wasn't this light, dancy beach girl anymore. I think she was trying to say this. She was talking how beautiful I used to look when I first went to high school. Tbh I had had enough & told her I don't want to talk about the past anymore because what she's saying is hurtful. Its like she's trying to say I'm still not that same innocent person anymore like I used to be, despite cutting those people out of my life years ago. It also makes me feel like a looser. I didn't fit in at school & with those 2 friends who were my best mates at the time, always made me feel left out. I always felt like I was the third wheel. I don't want to be different. That insinuates that I won't be able to make or mix with certain people according to my mum. I'm 22 & can't afford to move out. When she goes on like this, I just dont want to know her tbh. I also feel like I won't be able to be with someone that I love, because I'm too "different", so that person probably won't be interested in me anyway. It just makes me feel alone & a looser. IIN??
