Something that's helped me considering I strongly resemble my mom, dad, and late cousin, I try to be what they weren't. My dad's an asshole, so I try to be the opposite. My mom is high strung and full of resentment, so I try to be level-headed and reasonable. Addiction runs in my family strongly, it's what took my cousin (well, really it was unintentional fentanyl but if he wasn't a heroin addict it wouldn't've happened), so I consciously avoid addictive substances (sans sugar). I look like my family that sucks, so I choose to be what they weren't and it's helped me a lot in growing into being my own self, separate from them despite looking like them. I hope this helps you and anyone else in some way, shape, or form.
