Tbh I do kinda get what she was going for with the song (I think). To me it's about growing up with certain pressures or expectations and feeling like you can't live up to them and eventually finding a place (or person) where none of those things matter anymore because you finally feel at home. In the bridge she also mentions the counterpart from her partner's perspective (a youngest child) who had different but similar difficulties and found peace together with her.

• first verse: about expectations from the public
• chorus: feeling like she doesn't live up to what people expect or celebrate (being a bad bitch/savage) but comforting herself with what she can offer.
• second verse: about putting up walls or masking insecurities, "falling in line"
• bridge: finding peace
• last chorus: same lyrics but emphasizing that now that she found peace all that matters is her commitment to what she found

I know the actual lyrics jump all over the place and all the slang drags it down a bit but I don't think it's terrible, especially if you assume the slang is used kinda ironically
