Advice on becoming a niqabi

Assalamu alaykum warahmatullahi wa barakatuhu. Does anybody have really good motivating advice on becoming a niqabi. I really want to commit to it soon so bad but many doubts come to my head and I become hesitant. I'm 17 and I'm still in secondary school so I would only be wearing it occasionally but my plan and dream is to start fully commit when I get to college. I'm just so nervous even thinking about it but it's such a big dream I have. It will make me closer to Allah and allow me to fully focus on perfecting my character now that I'm detached from my looks. Peoples first impression of me will be of my character and not my looks. It just feels like a big commitment and sacrifice hiding my entire face and eyebrows like I keep asking myself am I truly ready for this. Marriage is the worst to think about (as the biggest hopeless romantic in the world I wanna cry thinking about this because I'm just a girl okay🥹). I worry how I will ever find a spouse if he can't see me how will he know if he's attracted to me physically. Just worries upon worries and doubts upon doubts. I don't want to be hesitant anymore I want to be firm upon this dream of mine. Does anybody have some solid advice or tips to keep me motivated?
