Don't know how I feel about growing breasts? :/

I'm 17 and started HRT a month ago and I'm loving everything about it so far, but like now my nipples are starting to change and my breasts are starting to form and I'm kinda nervous about it. I don't know, I kinda feel like I'm gonna miss having a flat chest and I'm sad it's gonna be gone forever. Hopefully I'll get used to having breasts once they come. Maybe I'm not ready to say goodbye to my male body? Anyone feel this way when they started seeing changes on HRT?
