Am I having real trans feelings?

I'm not here asking if I'm trans, but I'm unsure if I'm having real trans feelings that could mean I'm possibly a trans girl or I'm just some really insecure guy. Recently I've been having strong gender envious towards women mainly due to their presentation, long hair and overall beautiful faces, I usually wake up with really horrible thoughts about myself where I'd hate my face, hate my body and hate how I look. I avoid mirrors a lot and cringe every single time when I look at myself, I don't necessarily feel like a girl, but can't stop imagining myself as one as it does bring peace and calm. I've recently opened to the possibility that I might be a trans girl, but Idk if I'm having real trans feelings or I'm just some really insecure guy, I do have a female persona stuck inside my head too. I'd really like some advice
