Born Jewish but feel like an imposter for not having grown up Jewish

Long story short, I’m adopted and my birthmother died of cancer shortly after I was born. My current parents raised me Christian all my life (I never believed or followed it) and i didn’t have any interaction with Jewish culture or practices. However a few years ago my dad informed me that my biological mom was Jewish and since then I’ve been able to trace her family’s Jewish history back 15 generations into Europe. The problem is that no matter how much i try and engage with Jewish culture, I just continue to feel like I’m not Jewish enough or that I don’t belong and i get a weird sense of imposter syndrome even though I know I have significant Jewish heritage that i want to connect with. I guess im just looking for ways other people have gotten past similar feelings, any help would be appreciated.
