came out to mom, what now??

18m, I came out to my mom today and it went well. She offered to help me get a legal name change, specifically before I start college. I’m happy about it but I’m not sure how to bring up hormones. I fully intend to start HRT but I feel like she will think I’m moving too fast for her and the rest of the family to adjust. Just wanna know if anyone else felt like this when they came out? I’m feeling just as stuck as before honestly.
